Pet Diagnostics and Blood Work

Having a sick pet is stressful for both you and your pet. It can be challenging to know precisely why your pet is out of sorts. It would be nice to understand what ails our pets intuitively, but the reality is that most people are not able to. This is why veterinarian diagnostics are vital to helping a sick animal. At Oak Grove Veterinary Hospital in San Jose, we are committed to pet wellness. We believe that healthy pets are the happiest pets.


Signs of a Healthy Pet

Eyes: Dogs stare with intensity at their beloved owners. Raised and animated eyebrows are a sign of contentedness. The shape of the eye may also change from its standard shape when in distress. Cats will slowly blink their eyes when comfortable and happy.

Tail: A wagging dog tail is a sign of a happy dog. Pay close attention though, because that doesn't always mean they're feeling well. A cat twitching the tip of its tail is happy. However, cats thumping their tail may mean they are annoyed. 

Mouth: Dogs smile when they are happy. A relaxed or open mouth is a good sign in a dog.

Energy Levels: When a dog is energetic, that's a good sign that they are happy. However, some dogs will still play when not feeling well. Cats will often knead with their paws when they are happy.

Sounds: Many dogs squeal in excitement when going somewhere they love, such as a dog park. A cat purring is their way of saying they are happy and content. 

Signs of Pain or Distress in Your Pet

Dogs: Tail held between the legs is an indication of fear or unhappiness. Loss of appetite can be an indication of malaise. If a dog is sleeping restlessly and moving to new sleeping spots, it could indicate distress. A warm nose could indicate a sickness in a dog, but it isn't always a sign of illness.

Cats: Lethargy and loss of appetite can be a strong indicator of a sick cat.

Blood Work

Having blood drawn is never a pleasant experience, no matter who the patient is. In most of our routine pet exams, blood is drawn for a CBC – Complete Blood Count. This diagnostic testing tool will help us to detect conditions such as anemia, hydration level, immune response, possible infections, illness, and more. The CBC tests can help our team discover specific diseases such as leukemia and certain types of cancer. Another crucial blood test for dogs is the heartworm test. Heartworm is severe and can be fatal if not treated. The test for this parasite is done quickly by blood draw at our veterinarian's office. Other blood tests are performed to check an animal's kidney function, liver health, and pancreatic health.
