One of the most common but also frequently overlooked health problems for companion animals is dental disease. By age 3, most pets have some degree of periodontal disease. This occurs as a result of bacterial infection along the gum line, due to the formation of plaque. Plaque is a sticky substance containing millions of bacteria that forms along the tooth surface and gum line. Without frequent removal, plaque eventually hardens into tartar. Left untreated, this leads to gradual destruction of the gum tissue and supportive structures around the teeth, which can result in tooth loss. Not only is periodontal disease harmful and painful because it results in loss of teeth, but it can also cause damage to important vital organs such as the:

  • Heart
  • Liver
  • Lungs
  • Kidneys

When it comes to dental disease, most pet owners don’t realize the extent of the problem until it is quite advanced; hence the importance of yearly to twice yearly physical examinations including a thorough oral health care assessment. In the early stages of dental disease, your veterinarian can recommend home dental health care measures such as tooth brushing, dental treats and rinses, and dental diets. When professional dental care is needed for your pet, general anesthesia is necessary. Your veterinarian will discuss the procedures involved in a COHAT (comprehensive oral health assessment and treatment) plan with you when dental care is needed. Most often, this will involve a day at the veterinary hospital to plan and perform the procedures, which may include doing:

  • Pre-Operative Lab Work
  • IV Catheterization
  • General Anesthesia
  • Dental X-Rays/Digital Dental Radiographs
  • Teeth Cleaning and Polishing
  • Dental Charting
  • Tooth Extraction when indicated
  • Oral Mass Removal

Upon discharge, the veterinary team will review any instructions pertaining to post-dental medications, special feeding instructions, and when to resume home dental care. Your pet will thank you for remembering to take care of his or her mouth, and live a longer and happier life as a result.

When your pet is sick or injured, they can’t tell us what’s wrong. A thorough physical exam and history (symptoms you’ve noted at home) are the first important step. If the diagnosis is not immediately evident upon initial assessment, your veterinarian will recommend specific diagnostic tests.

Diagnostic testing is an important step in the development of a treatment plan for your pet, allowing your veterinarian to most effectively target the underlying problem(s) and assess the probability of successful treatment. Your veterinarian can explain the purpose of each diagnostic test for your pet, and help prioritize which tests may be most helpful in determining the cause of your pet’s illness.

Diagnostic Testing (in-house or via outside lab) May Include:

  • Blood Chemistry & Blood Count
  • Hematology
  • Urinalysis
  • Coagulation Panels
  • Thyroid Levels
  • Antibody Titers
  • Digital Radiology
  • Ultrasound
  • Electrocardiography (EKG)
  • Intestinal Parasite Testing
  • Cytology Evaluation
  • In-House FeLV/FIV Testing
  • In-House Heartworm/Lyme/Ehrlichia/Anaplasma Testing
  • Biopsy
  • Schirmer Tear Test
  • Tonometry (eye pressure)
  • Eye Staining (eye ulcers)
  • Blood Pressure

Dietary Planning & Nutrition

  • Weight Management Consultation
  • Disease Treatment

Emergency & Urgent Care

In emergency, seconds count. When you arrive with your pet on emergency or urgent care basis, our highly trained staff will perform an immediate triage assessment to assess the stability of your pet and need for emergency medical intervention.

The first component of basic triage is assessing your pet’s level of consciousness, airway/breathing (labored breathing or choking, lack of oxygen), circulatory status (pale gums or weak pulses, racing heart), and pain score. Patients needing urgent medical attention, upon consent, will be moved to our treatment area for immediate doctor assessment and commencement of emergency care and, hopefully, stabilization.

Emergency Capabilities:

  • IV Catheter
  • IV Fluids
  • Oxygen Supplementation
  • Isolation Area
  • Pain Relief Medications
  • Radiographs
  • Ultrasound
  • Bloodwork
  • Urine Testing
  • Vital Monitoring

As your pet is stabilized, your veterinarian will review a diagnostic plan and financial estimate with you.

At times, your pet may need advanced care at a referral or specialty center. When this is the case, our staff will discuss options for transfer and referral. Your primary veterinarian will stay abreast of your pet’s status at the emergency facility.


  • Ear cleaning
  • Nail trim
  • Nail Dremel
  • Anal Gland Expression
  • Mat Removal

In-House Laboratory

When your pet becomes ill or in event of an emergency, timely diagnostic test results are extremely important to help your veterinarian determine the best treatment plan.

We have state-of-the-art in-hospital laboratory equipment capable of yielding lab results within minutes.

Tests Available:

  • Complete Blood Cell Count – Can indicate problems such as anemia, dehydration, infection, auto-immune disease, and certain types of cancerous conditions
  • Blood Chemistry Testing – Can assess liver function, kidney function, blood sugar, blood proteins, calcium and phosphorus levels, and pancreatic function
  • Thyroid Hormone – Can assess low thyroid function or high thyroid function that might need stabilization with medication
  • Electrolyte Tests – Sodium, potassium and chloride levels may be abnormal when your pet is dehydrated or having fluid losses through vomiting or diarrhea. Intravenous fluids and/or supplementation may be indicated when electrolytes are severely deranged.
  • SNAP tests – Point-of-care “snap” tests are available for certain infectious diseases such as Feline Leukemia and Feline Immunodeficiency Virus, Canine Parvovirus, Giardia, and Leptospirosis.
  • Microscopy – Microscopic evaluation of bodily fluids including blood, urine; samples of skin and ear secretions, and needle biopsies of swellings or tumors can be performed in-clinic to assist in the diagnosis of systemic diseases, urinary disorders, skin and ear diseases, and differentiation of benign vs. cancerous tumors.

Our veterinary team will help explain which tests are most important for your pet. It is very important to us to include you in the decision-making process for your pet.

Parasite Control

Pets are a part of our families, and preventing parasite infestations is an important part of keeping them healthy. Both ectoparasites (external parasites) and endoparasites (internal parasites) can affect your pet at some point in their life.

Some Common Parasites:

  • Fleas
  • Ticks
  • Roundworms
  • Hookworms
  • Whipworms
  • Tapeworms
  • Heartworm

Some Diseases Caused by Parasites:

  • Bartonella
  • Lyme Disease
  • Anaplasmosis
  • Ehrlichia
  • Rocky Mountain Spotted Dever
  • Dermatitis

Many parasites are also a health risk to humans and are considered zoonotic – meaning they can be transmitted from animals to people. For example, if a person accidentally ingests roundworm eggs, the larvae can migrate in the body and cause organ damage and potentially blindness.

Since parasites pose a health risk to your family and pets, it is important to keep your pet on a year-round parasite prevention program. There are several preventives that when used properly, are very effective at greatly reducing the risk of your pet acquiring these parasites. The best prevention for your pet will be discussed at his/her annual physical exam.

For more information about pets and parasites, visit, and consult with one of our friendly staff!

Puppy & Kitten Care

We recommend bringing your puppy or kitten in as soon as possible after acquiring him/her.  Often times, we see puppies and kittens with parasites, ear infections, urinary infections and other issues at their first visit.  Depending on the age of your new pet, they will likely need additional vaccinations as well. During this first visit, the doctor will outline a wellness plan for your pet.  This will include multiple visits over the course of the first few months as your pet receives the appropriate vaccines at the appropriate times.

Getting your new puppy or kitten off to a healthy start sets the stage for their lives as healthy adults.  The first visit will be packed with information, but do not worry as we will give you a helpful booklet with it all summarized.  During this visit we will perform a physical exam and discuss core and elective vaccines, fecal testing for intestinal parasites, dewormings, preventative care and other important elements to ensure great health!  You will leave with a puppy or kitten kit that will help you get your pet off to the best start.

Our knowledgeable staff will be there for you to help with any questions you may have with your new family member.  We realize that adding a new family pet can come with lots of questions… but don’t forget, we’re here to help, so please don’t hesitate to send us an email with anything that comes up.

Senior Pet Care

We love Senior Pets! Senior pets have special needs, and benefit from more regular veterinary visits compared to their younger counterparts. We recommend senior pets, or those over 8 years old, come in every 6 months for complete physical exams. Since pets age much quicker than humans, it is very common for new diseases and illness to show up in a short time frame. Performing annual bloodwork on your older pet can help identify early stages of medical problems that might go unrecognized, and progress significantly without treatment.

Age-associated conditions include:

  • Arthritis
  • Dental Disease
  • Heart Disease
  • Liver Disease
  • Kidney Disease
  • Endocrine Disorders
  • Cognitive Dysfunction

Sick Visits or Office Visits

Some reasons to schedule an office visit:

  • Behavior Changes
  • Bowel Issues
  • Skin Issues

Wellness Care

Preventive veterinary care is the cornerstone of keeping your pet their healthiest so that you and your pet can have more great years together. Since pets age more quickly than people do, it is critical to have regular physical examinations done to assess your pet’s health. We recommend annual physical exams for healthy pets under 8 years old.

During routine preventive exams, your veterinarian will assess:

  • Overall Body Condition
  • Eyes
  • Ears
  • Nose
  • Mouth
  • Throat
  • Heart and Lungs
  • Abdominal Organs
  • Musculoskeletal System
  • Neurologic System
  • Urogenital System
  • Lymph Nodes
  • Skin/Coat

When health problems are identified, a medical plan will be discussed with you and the veterinarians.

If your pet appears to be healthy for routine preventive care, your veterinarian will discuss which immunizations are advised, as well as parasite prevention including heartworm disease, intestinal parasites and ectoparasites (fleas, ticks, etc.).

Annual age-appropriate lab tests, testing for heartworm and/or tick-borne diseases, and fecal tests for parasites may also be recommended for your pet. Finally, your pet’s nutrition, diet and exercise routines can be assessed and optimized to help your pet be in best physical condition for their lifestyle and age.
