Just like humans, an animal's diet directly affects its overall health and well-being. Allowing a pet to overeat, or to consume the wrong foods, may lead to a wide variety of ailments including obesity, diabetes and arthritis.

Did You Know?

Over 50% of dogs and cats in the United States are obese or overweight.

Proper Nutrition

Although we think of our pets as family members, they shouldn’t be allowed to eat like us. Maintaining a proper diet will help keep your pet at a healthy weight. Be sure not to overfeed, and that you are providing a diet tailored to your pet's breed, age, weight and medical history.

Common Foods To Avoid

Think twice about feeding your pet table scraps. Common foods such as chocolate, grapes, raisins, onions and garlic could be dangerous to an animal. Some non-food items like lily plants and antifreeze are also toxic to pets. Check with your veterinarian if your pet has ingested anything questionable.
Pet Nutrition


Growth Diet

Growing puppies and kittens need more nutrient-dense food than adults. Ask your veterinarian which food is right for this stage of life. Cats switch to an adult diet right after being spayed or neutered, no matter what the age, to decrease the likelihood of obesity and related conditions.

Adult Diet

Selecting an adult dog or cat food that will keep your pet healthy and energetic starts with knowing your pet's lifestyle. Does your dog weigh just the right amount and go for long walks daily? Or is it a lap dog that loves nothing more than to snooze the day away? Talk to your veterinarian about these issues to help guide you in choosing the best food for your pet.

Senior Diet

Your senior dog or cat may need fewer calories, less fat, and more fiber as he or she ages. Many older pets can continue eating the food they always have – just a little less to compensate for not being as active. Check with your veterinarian which food and amount is best for your pet.


Every pet ages differently. Your veterinarian can help you determine the best diet for your pet's needs.

Spaying or neutering can protect your pet from serious health and behavioral problems later in life. It also helps control the stray animal population.

Spaying or Neutering Reduces the Risk of...

Uterine Disease

Known as a pyometra, this is a potentially life-threatening condition which can be very expensive to treat. It is 100% preventable if your pet is spayed.

Mammary Tumors (Breast Cancer)

Over one-half of all mammary tumors are malignant and can spread to other areas of the body. Early spaying, prior to your pet beginning its heat cycles, significantly reduces the incidence of tumor formation.

Testicular Cancer

This cancer, as well as prostatitis (an infection causing malignant or benign swelling of the prostate), can be greatly reduced with early neutering.


Behavioral Problems

Unwanted behaviors such as dominance aggression, marking territory and wandering can be avoided with spaying or neutering.


There are more puppies and kittens in shelters than there are people willing to provide them with love and care. Sadly, many are euthanized. Spaying or neutering can help reduce the number of animals in need of homes.Cat and Dog graphic

Make your pet's well-being a priority. See your veterinarian regularly and follow these tips to keep your pet happy and healthy.


Your veterinarian will give you a recommendation for a high quality and nutritious diet for your pet, and advise you on how much and how often to feed him or her. Diets may vary by species, breed and age.


Microchipping is a safe and permanent identification option to ensure your pet's return should he or she get lost. Ask us about the process and get your pet protected.


Always keep your dog on a leash in public, and your cat indoors to protect them from common hazards such as cars and other animals.


Frequent brushing keeps your pet's coat clean and reduces the occurrence of shedding, matting and hairballs. Depending on the breed, your pet may also need professional groomings.

Dental and Oral Health

Brush your pet's teeth regularly and check with your veterinarian about professional cleanings as well as dental treats and products available to help prevent bad breath, gingivitis, periodontitis and underlying disease. Although your pet's teeth may look healthy, significant disease could be hidden below the gum line.



Be sure to spend at least 15 minutes a day playing with your cat to keep him or her active and at a healthy weight. All dogs need routine exercise to stay fit, but the requirements vary by breed and age. Ask us what's best for your dog. Doggy daycares and boarding facilities are other ways to help to burn off some energy and socialize your pets.


Enroll your dog in training classes to improve his or her behavior with pets and people. Cats need minimal training. Be sure to provide them with a litter box beginning at four weeks of age.

Environmental Enrichment

Entertain your pet's natural instincts by using toys that encourage them to jump and run. Cats especially need to fulfill their instinct to hunt – provide interactive toys that mimic prey like a laser pointer or feathers on a wand. You can also hide treats in your pet's toys or around the house to decrease boredom while you're away.Pet Care at Home


Be Your Pet's Guardian Angel

Call us if your pet experiences vomiting, diarrhea, poor appetite, lethargy, trouble breathing, excessive drinking or urinating, wheezing or coughing, pale gums, discharge from nose, swollen eye or discharge, limping, and/or difficulty passing urine or stool as these may be signs of illness.

Every animal is unique, and the start of each stage of life calls for different home and veterinary care. Check with your veterinarian to establish a proactive wellness plan to keep your pet happy and healthy throughout its life.

Annual Wellness

Puppies and kittens must receive a series of properly staged vaccines and physical exams. During these exams, your veterinarian may also recommend parasite preventatives or lab tests.

Adult pets will need to continue visiting the veterinarian annually for physical exams, recommended vaccines and routine testing.

Senior pets can develop similar problems seen in older people, including heart disease, kidney disease, diabetes and arthritis. Your veterinarian may recommend biannual visits to ensure your pet's quality of life.


Females spayed before their first heat cycle will be less likely to get uterine infections, ovarian cancer and breast cancer. Males neutered at any age will be less likely to get prostate disease. Spaying or neutering also helps prevent behavioral problems like marking and escaping. Talk to your veterinarian about spaying or neutering your pet.


Pets require different types of food to support each life stage. Growing puppies and kittens need more nutrient-dense food than adults while adult dogs and cats need food that will keep them healthy and energetic. Your senior dog or cat may need fewer calories, less fat, and more fiber as he or she ages. Talk to your veterinarian to determine what's appropriate for your pet.

Adult dogs should stay active with daily walks and one-on-one training. Keep your adult cats fit by using toys that encourage them to run and jump, and be sure to give them at least 15 minutes of playtime a day.

Weight management of your senior dog or cat is extremely important to ensure they are at an ideal body weight and able to move around comfortably.


Behavioral issues are a major cause of pet abandonment. Begin training your puppy or kitten right away to prevent bad habits and establish good ones.

Start house training your puppy as soon as you get home. Keep your puppy supplied with plenty of chew toys so he or she gets used to gnawing on those and not your belongings.

All cats need a litter box, which should be in a quiet, accessible room. Place your kitten in the box after a meal or whenever it appears he or she needs to go. Be sure to scoop out solids daily and empty it out completely once a week. The number of boxes in your household should be the total of number of cats plus one.

Rabbits make excellent pets. They are available in quite a number of variations, including short fuzzy hair, like the Rex, long-haired, like the Jersey Wooly, dwarf lops which are small, and rather large breeds such as Artic Hares.

Rabbit in CageHousing

  • Rabbits are very curious critters. They are also very ardent chewers. In general, it is best to keep your rabbit caged when not supervised.

  • Provide a roomy cage, six times the size of the adult rabbit.

  • The door must be large enough for the litter box, and toys should be provided in the cage.

  • Wire cages are readily available and work well by allowing the feces and urine to fall through the cage. However, it will still be necessary to keep the cage and the bedding clean.

  • Rabbits that are allowed to come in contact with their urine for long periods of time can suffer urine burns (sores) on their hocks. Place a resting board covering a part of the cage floor for the rabbit's comfort.

  • When lining your rabbit's cage, kiln-dried pine shavings or paper shavings are preferred. Cedar, pine or chlorophyll shavings should not be used.

The pleasures of being outdoors include fresh air, sunshine, and freedom to run, chew and dig. But for a rabbit, being outside can also be dangerous, most importantly from predator attack. Such attacks primarily occur at night, but can also happen in the daytime.

Hutches and cages do not provide enough protection to make it safe to leave a rabbit outdoors 24 hours a day. Even if the predator is not able to get into the cage, the rabbit may panic, injure herself, or die from shock or heart attack. Raccoons can open hutches. Coyotes, owls, hawks, possums, cats and dogs are also threats. For safe daytime exercise, we suggest a pen within your fenced yard, one with a top, bottom and sides. We strongly urge you to bring your rabbit in at night.


Proper handling of your rabbit is essential. Always support the hind end of your rabbit when you pick it up. Never pick up a rabbit by its legs or ears. Rabbits will frequently injure their backs when picked up without supporting the hind end.

Handle your rabbit often when it's young, to increase its acceptance of affection when it's older. Pet him on the broad area on top of his nose to help him get use to you. Never let him jump from heights.
