Our Veterinary Services

Companion Animal Veterinary Associates provides a comprehensive range of services to meet the needs of you and your pet, regardless of age, breed or health status.

Wellness and Preventative Care

We recommend yearly wellness examinations for all pets. Physical examination of growing puppies and kittens as well as senior and geriatric patients will be recommended on a more frequent basis. Our wellness appointments incorporate a full physical exam, discussion about recommended vaccinations, education and counseling about appropriate parasite prevention and testing, and for some pets, metabolic testing and lab work.

American Heartworm Society


Companion Animal Veterinary Associates recommends that all pets be microchipped. This not only provides a permanent means of identification for your pet, it also helps to ensure that your pet is more likely to be returned to you if unexpectedly lost. Please ask us about microchipping your pet today.

Senior Care

As our pets live longer, appropriate care that is directed towards their changing needs is a must. The veterinarians and staff at Companion Animal Veterinary Associates want to give you the information and tools to provide your mature pet with the best quality of life. Conditions that more often affect our mature animals include dental disease, vision impairments, arthritis, skin growths, obesity, heart disease, and cognitive decline. Routine lab work can help to identify early metabolic changes, including diabetes, thyroid disease, and kidney disease. For most diagnosed conditions there are medical and nutritional treatment options that can be instituted to help manage the medical condition and allow your pet live with good quality of life.

Dental disease is the most common health condition in dogs and cats, and often is a significant factor for pets as young as 2 years of age. The doctors and staff at Companion Animal Veterinary Associates will provide you with the education and tools needed to help keep your pet’s oral health in good condition. We provide oral health assessments for your pet, routine dental prophylaxis, and treatment of teeth affected by tartar, periodontal disease or trauma. Dental radiology (x-ray) is an important diagnostic tool that we utilize to help make the best treatment recommendation for your pet.

General Surgery

Our veterinary and nursing team provides individualized care for your pet requiring general surgery. We provide services ranging from dermal growth removals, spay and neuter surgeries, bladder and abdominal surgeries, and select ocular surgeries. We always recommend a pre-surgical appointment so that we can fully evaluate the health of your pet prior to surgery and develop an individualized care plan for your pet. This also gives us an opportunity to review anesthesia, which is a common anxiety inducing term for most pet parents, and the lengths we take to make it is as safe as possible. Financial expectations and post-operative home care will be reviewed prior to any scheduled surgery as well.

Spaying and Neutering


Companion Animal Veterinary Associates utilizes advanced digital radiology technology in order to achieve high quality x-ray images in the most efficient manner. Radiographs can be integrated into an outpatient appointment, but occasionally sedation and/or a longer appointment time may be indicated.

Health Certificates

Pets require a formal health certificate within 10 days of any interstate or international travel. Health certificates require a full physical examination. For pets traveling internationally, the requirements for entry vary from one country to another. We are happy to help you in completing the necessary requirements and documentation in preparation for travel. Information regarding each country can be found on the USDA website. Crosier is certified by APHIS to provide international travel certificates.

Medicine and Surgery

Dr. Crosier provides wellness, medical and surgical care for variety of small mammals including rabbits, ferrets, guinea pigs, rodents, and hedgehogs. She also provides wellness and medical services for avian companions. Often these animals hide signs of illness very well, so it is important to schedule routine wellness exams and to have these special pets checked at the first signs of illness. Grooming services such as nail and wing trims can be scheduled for current patients that we have seen for a full examination within the last 12 months.

Nutrition and weight management is an important part of your pet’s overall wellness. Pet owners are presented with many options for pet foods and the choices can seem overwhelming. We will provide you with recommendations regarding the appropriate food and amounts to feed your pet based on body condition, activity level, and overall health. In some cases, a prescription diet may be indicated to help manage a chronic medical condition.
