THE NORWICH TERRIER
The Norwich Terrier comes from the U.K, and is part of the UKC/AKC Terrier group. This is a breed that was originally trained to kill rats. This dog breed was used in packs to travel in foxhunts. Even so, they are more sociable than a regular terrier.
Brief History
The Norwich Terrier and the Norfolk Terrier were known as the same breed until 1964. After that, the main difference would be the Norwich Terrier’s prick ears. The Norwich Terrier was bred during the 1870’s and 1880’s. Undergrads at Cambridge University came to enjoy this dog breed. This dog breed became dorm-room ratters for Cambridge and nearby stables. This breed then was named Trumpington Terriers. One of these dogs was bred numerously at a stableyard, and sired Terrier pups. The breed then became the Jones Terriers in the U.S. The UKC and AKC recognized the Norwich Terrier in the 1930’s. Both Norwich and Norfolk Terrier are closely related.
Physical Features
The Norwich Terrier is spunky and alert. This dog breed is the smallest working terrier. With dark eyes that are oval-shaped, their skulls are broad and slightly rounded. The body is moderately short, and the tail is of medium length, and docked. The hindquarters are strong and muscular.
The Norwich Terrier has a wiry coat that lies close to their bodies, and has an undercoat. The coat on their necks and shoulders forms a mane. The coat can be shades of black and tan or grizzle, red, or wheaten. Their temperaments are happy, fearless, and alert.
Average Height:
9-10 inches
Average Weight:
11-13 pounds
Life Expectancy:
12-15 years
Temperament
The Norwich Terrier is alert, fun loving, and affectionate. This is a good natured dog breed that enjoys children and other dogs. In order to spend time around other small animals it’s a good idea if they’re socialized first. This dog breed is fearless and highly trainable. Positive dog training and socialization needs to start during puppyhood. The name Terrier comes from the Latin word “terra” meaning earth. These dog breeds were first used to dig tunnels so that they could chase rats and other small prey. These are high- energy dogs that enjoy exercising and free play.
Special Needs
The Norwich Terrier needs to have a securely fenced backyard or garden. This dog breed is known for its escapades, and tends to dig beneath fencing to escape. Socialization with cats, children, people, and other dogs is necessary starting during the first four weeks of puppyhood, and continuing for the dog’s lifetime. Positive dog trainings should focus on maintaining the happy temperament that this breed displays. Harsh or loud reprimands tends to negate any positive bonding, and subjects a dog to unnecessary stress and possible trauma.
Possible Health Concerns
The Norwich Terrier is an active and healthy dog breed that may be susceptible to the following health conditions:
Hip Dysplasia: This is a hereditary condition that affects this dog breed. HD is an abnormal development of the hip joint in dogs. It’s generally characterized by a loose joint, then degenerative joint disease. Dogs should be fed a high-quality diet geared towards their life stage. Excessive growth, types of exercise, nutritional factors, and hereditary factors all come in to play with hip dysplasia. Consult with your veterinarian for expert advice.
Epilepsy: An inherited disease that causes seizures. Dogs will generally require treatment with anticonvulsants from their veterinarians.
Degenerative Myelopathy: This is a progressive neurodegenerative disease that may be found in the Norwich Terrier. It is caused by the SOD1-A gene. It happens during adulthood. Some symptoms may include limb weakness, muscle wasting, muscle tremors, and stumbling. Consult with your veterinarian.
Upper Airway Syndrome: This is a respiratory condition that presents as noisy breathing to critical distress. The condition is breed specific, can occur without warning, and may be fatal.
Dental Disease: This is common in smaller dog breeds. Brushing your dog’s teeth everyday, followed by twice yearly dental cleanings, will reduce the chance for periodontal disease.
Luxating Patellas. This is a hereditary condition that is caused by the abnormal development of the kneecap(patella). X-rays will aid in seeing the severity of the displacement. Treatment usually involves surgical options.
Exercise
The Norwich Terrier needs moderate exercise with brief bouts of fast activity like running after a tennis ball. This breed should never be over-exercised. They benefit from a few daily walks at a moderate pace with lots of off-leash runs at the beach or dog park.
This breed needs plenty of socialization like going to the dog park, or out and about the neighborhood. If not exercised sufficiently, they can become overly cranky and anxious. They should not be allowed to jump off tables, run up flights of stairs, or overexert themselves. Swimming is a great exercise for this small dog breed that will promote bone and joint strength.
Nutrition
A high-quality dog food for the appropriate life stage is recommended. Dog parents should assess their dog’s activity level, age, breed, and any medical conditions that he or she may be prone to.
Look for dog food formulas that contain ingredients like duck, eggs, chicken, lamb and Wisconsin cheese, fruits and vegetables. Another factor that comes into play is that the dog food formula does not contribute to plaque buildup. It should not contain sugars, salt, or added preservatives.
Grooming
The Norwich Terrier has a double coat. The outer coat is harsh, and almost 100% waterproof. The undercoat is soft and insulating. Clipping is practical, yet may remove the colored tips from the coat. The coat texture will be much softer when clipped.
Daily grooming is necessary with bathing as needed, since this breed loves playing around in the bushes and in mud. The Norfolk Terrier is active, and does well with regular grooming. Regular ear cleaning and daily tooth brushing is needed to prevent tartar buildup. Nails need to be trimmed as needed. As with all dog breeds, it’s necessary to bring your dog in for a twice yearly dental cleaning.
This bright and quirky dog breed is delightfully playful, and always ready for adventure. They enjoy hikes, swims, boat rides, or just hanging out next to you.
THE SIAMESE CAT

The Siamese is one of the oldest and most famous cat breeds, with ancestral roots in Siam, known today as Thailand. In Victorian England it gained the nickname “Royal cat of Siam” and was highly favored for its striking looks and an elegant coat color. These cats are beloved for their intelligent and curious natures.

For many centuries, travelers to ancient Thailand brought home art and manuscripts that depicted the Siamese in full stature. Their migration to the western lands began during the late 19th century when they were used as show cats, most notably at the London Crystal Palace cat show. From here, they were introduced to the states when a US diplomat stationed in Thailand gave President Rutherford B Hayes a Siamese cat as a gift.
Physical Features
The Siamese coat is perhaps one of its most unique physical features for its color and glossy appearance. There are two types of Siamese cats: traditional and show. Traditional Siamese cats have apple shaped heads while show Siamese cats have wedge-shaped heads with ears that are large and triangular in shape. The show Siamese has a tubular body with long legs and flat paws. Both have striking almond-shaped blue eyes that sparkle with adoration and curiosity.

Grooming
The short Siamese coat is easy to groom and maintain. While they do shed, if you adhere to a strict grooming routine, it shouldn’t be too cumbersome. Comb the coat on a weekly basis using a stainless steel comb to remove any dead hair.
Siamese cats are ideal for owners who crave companionship and affection. They are highly intelligent, hyper-vocal, and love staying active.

THE FRENCH BULLDOG
The French Bulldog, also known as the Bouledogue Francais, or Frenchie, looks like a miniature Bulldog. The Frenchie originated from France, and was bred from miniature Bulldogs as a companion dog. This is a muscular and heavily boned breed, with a short tail, large bat-like ears, and heavily wrinkled skin around the head, neck and shoulders. Frenchies are fun and affectionate dogs.
Brief History
During the late 19th Century, the French Bulldog was bred as a companion dog by English lace workers who emigrated to France. The English dogs were bred with local dogs in France, and soon this breed became fashionable.
Physical Features
The French Bulldog has a large, square head with an upturned nose, and a short and wrinkled muzzle. Their ears are naturally upright, rounded with a batlike appearance. Their skin is soft, with wrinkles at the head, neck and shoulders. Coats can be brindle, fawn, white, or brindle and white.
Average Height:
11-13 inches
Average Weight:
18-28 pounds
Life Expectancy:
10-12 years
Temperament
This breed is affectionate, alert, curious and intelligent. They get along with other dogs and people and make for great guard dogs, but don’t bark as much as smaller breeds. French Bulldogs adapt easily to apartment life since they don’t require a lot of exercise. Although this breed can be stubborn, they are easy keepers, and do best with positive training and plenty of socialization. This breed is gentle with children, and also enjoys living with single pet parents.
Special Needs
This is a brachycephalic breed, also known as a short-faced or snub-nosed breed, and needs to have plenty of protection from heatstroke. This breed does well indoors during extreme temperatures. They also need to be supervised when around water or swimming pools – they can’t swim due to their front-heavy build.
Possible Health Concerns
Since French Bulldogs have flat faces, they are more sensitive to anesthesia. They may also be susceptible to:
Atopic Dermatitis. A common allergic skin condition. Constant itching and scratching leads to hair loss and scabbing, resulting in secondary bacterial infections. Treatment involves antihistamines, change of environment, essential fatty acid supplements (EFA), and medicated shampoos.
Congenital Vertebral Anomalies. French Bulldogs may have deformities of the bones in the spine resulting in pressure of the spinal cord, progressive pain, and possibly loss of hind limb function.
Brachycephalic Syndrome. Dogs with this problem will snore, snort and breathe through their mouths.
Elongated Soft Palate. A long palate may result in blockage of part of the airway into the lungs. This causes breathing difficulties, and can be corrected surgically with a high success rate, most especially if the dog is under a year.
Heatstroke. French Bulldogs are more susceptible to heat than many other dog breeds.
Exercise
The French Bulldog does well with light exercise, such as a short walk around the block or brief trip to the dog park. This breed enjoys dog training classes, obedience, agility and some rally sports. However, they should never exert themselves during hot or humid temperatures.
Nutrition
Every dog is different, and some brands of food will be better suited for certain dogs. When it comes to dog foods, understanding your pet’s current health and nutritional needs is important. Consult with your veterinarian for advice. There is no best diet since all French Bulldogs have different dietary needs, so it’s always smart to find the best food to match each individual dog.
Grooming
Daily brushing with a rubber mitt or medium bristle brush will aid in removing loose hair and keep the coat healthy and shiny. Make sure the loose folds around their necks are kept clean and wiped daily, and regularly trim their nails.
Because the French Bulldog is a low energy breed, they make for a wonderful, family-friendly adoption.
THE MINIATURE PINSCHER
The Miniature Pinscher has been around for hundreds of years and is even older than the Doberman, though not related. It is believed that the Min-Pin was originally breed to be a ratter, but quickly became one of Europe’s favorite Toy dog breeds. Their quirky natures also make them very popular in the U.S.
Brief History
The Miniature Pinscher was bred around 1895 and is a part of the AKC/UKC, Toy Dog Group. Historians believe that the Min-Pin is a cross of the Dachshund and the Italian Greyhound. The German Pinscher was also crossed in at some point, though WWI slowed its development. Once the war concluded, German dog breeders and dog fanciers continued breeding the Miniature Pinscher. The Min-Pin arrived in the U.S in the 1920’s. Although the Min-Pin is a small dog breed, they make highly capable watch dogs.
Physical Features
The Min-Pin is a well-balanced, sturdy, and small dog breed. This dog breed has a compact and muscular wedge-shaped body. With a narrow, tapering head and a flat skull, the Min-Pin has a strong muzzle. Their heads are well-balanced with a black nose. Chocolate-colored Min-Pins typically have a brown nose to match. This pup’s eyes are alert, oval-shaped and so brown that they’re almost black. Ears may be cropped or natural. The Min-Pin has a short, smooth and straight coat. Coloring is either red, stag red (red with black mixed in), black with rust markings, or chocolate with rust markings.

Temperament
The vigorous and fearless Miniature Pinscher is a proud, alert, and well-groomed breed. They typically are extremely confident with tremendous spirit and may seem arrogant to other dogs. This breed may be wary of strangers and is sometimes aggressive with other dogs.
The Min-Pin will be combative if provoked. This dog breed does well with positive dog training and socialization starting at puppyhood. That said, dog parents need to protect this super confident little guy from larger dogs.
The Min-Pin does well with apartment living. Additionally, this spirited dog breed enjoys being indulged, and is very popular when visiting bookstores and cafes. The Min-Pin does well with all the attention he gets when out and about. They make spirited, loyal family additions.
Special Needs
The Min-Pin makes a wonderful active and alert companion dog, but definitely needs plenty of socialization starting the first four weeks of puppyhood. They may occasionally have aggressive tendencies towards strangers and other animals, so the sooner this breed starts with socialization and positive training, the better. Although you may think that because this dog breed is small, this is a laid back dog breed, keep in mind that the Min-Pin’s original purpose was for ratting. This dog breed is amenable to city living, but must have daily walks and trips to the local dog park. The Min-Pin often makes for a wonderful travel companion. This breed should always be supervised around children, as they tend to be short-tempered.
Min-Pin pups that have been socialized early tend to be more relaxed later on in life in different environmental situations. They also are more tolerant of children, other animals, and people. The more socialization and positive training your Min-Pin gets, the nicer they’ll be.
Children should also learn not to disturb the Min-Pin when eating, not to carry him around or be aggressive. This dog breed generally prefers adults to children and does well with a relaxed environment. That said, the Min-Pin is prone to separation anxiety when left alone. This breed may also be difficult to housetrain, especially male Min-Pins.
The Min-Pin has a high prey drive and may be possessive over food and dog toys. They love affection and benefit from a lot of TLC.
Possible Health Concerns
Cervical Dry Disk: This is a common neurological problem found in Min-Pins. Cervical disk disease results in the loss of flexibility in the intervertebral disk. The discs no longer act as shock absorbers. Symptoms include stiff head and neck, severe muscle spasms and possible paralysis.
Patellar Luxation: This is typically congenital in Toy breeds like the Min-Pin, and may occur at the same time as other limb abnormalities. It is caused by the abnormal development of the kneecap(patella). X-rays will aid in seeing the severity of the displacement.
Legg-Calve- Perthes Disease: This is the deterioration of the top of the femur (femoral head), and is seen in Toy and smaller dog breeds. It is characterized by a lack of blood supply, and the destruction of blood vessels of the bone. Some symptoms may include hindlimb lameness, loss of muscle in the thighs, and pain when moving the hip joint. Treatment involves surgery.
Epilepsy: This is an inherited disease that causes seizures.
Hypothyroidism a deficiency of the thyroid hormone and can cause weight gain in dogs, as well as constipation and cold sensitivity. Treatment typically involves thyroid hormone supplementation.
Canine Mucopolysaccaridoses: The Min-Pin is especially prone to this. It is a group of metabolic disorders that are caused by an accumulation of glycosaminoglycans or mucopolysaccharides. Symptoms may include severe bone disease, dwarfism, degenerative joint disease, and eye cloudiness.
Exercise
The Miniature Pinscher is a sturdy and headstrong little fellow and needs to be walked regularly to avoid cabin fever. This breed tends to bark a lot, and will become demanding if he’s left alone too often. That said, this breed learns very fast, so don’t let bad habits set in. The Min-Pin does well with frequent visits to the dog park and running off leash.
If this breed is not exercised properly, it may become aggressive and very rowdy. Long hikes, walks, canine surfing, and obedience classes are great for this loyal and alert pup. The Mini-Pin wants nothing more than to be with their pet parent.
Nutrition
The Min-Pin does well on a high-quality dog food. If you’re opting for home-prepared dog food, consult with your veterinarian first. All dog food diets should have the approval of a veterinarian. Smaller dog breeds tend to pick up weight easily and are prone to being overweight.
The Lagotto Romagnolo
Grooming
The Min-Pin is a low maintenance dog breed with minimal grooming required. Daily combing with a soft brush is all that’s needed. Consult with your veterinarian as to the healthiest flea and tick products. Your Min-Pin will need to be bathed weekly. With so many natural dog shampoos and conditioners available today, make sure that you use one that is appropriate for your Min-Pin’s skin and coat. Tearless shampoos work well. Some sensitive Min-Pin’s may not do well with scented products and may only be able to tolerate hypoallergenic products.
Min-Pin’s require monthly pedicures. If you’re not comfortable doing this, consult with a professional dog groomer or veterinarian. The Min-Pin’s ears also need to be regularly cleaned. This can be done by wiping a cotton ball or canine wipe, moistened with a canine ear cleaner, inside the ear. To prevent chronic gum disease, brush your Min-Pin’s teeth every morning. Professional dental cleanings are recommended twice a year.
CAT HEALTH: A CHECKLIST
All cat owners know cats are independent creatures and do not require a lot of your time. Cats love to sleep and hide in safe places; however, they also want and need attention. They need scratching posts, climbing towers, feeding, grooming and other loving care. Because of their independent nature and desire to be separated from human activity part of the time, many cat owners believe they do not have to interact with their cats on a daily basis. In reality, cats need daily attention from their human family to be at their best.
VACCINES FOR PETS
Vaccines are laboratory prepared substances acquired from killed or weakened forms of a causative agent of disease for the purpose of building the immunity of the body against infectious diseases. Puppies or kittens acquire passive immunity through lactation from the mother’s milk as well through the placenta. With time this immunity decreases and vaccinations are necessary to build the bodies immunity (active immunity). Most of the diseases vaccinated against are incurable, highly infectious and often lead to death.
