Cancer is the leading cause of death in dogs and cats, particularly when the animal is over age 10. According to the American Veterinary Medical Association, 50 percent of senior dogs and 33 percent of senior cats die of some type of cancer. No matter what the age of the pet, a cancer diagnosis often comes as a complete shock to his owner. That is because dogs and cats are good at hiding their symptoms and don't have the ability to verbalize that something is wrong. 

As a concerned pet owner, it's up to you to know the signs of cancer so you can seek immediate treatment if your pet displays any of them. While having some of these symptoms doesn't necessarily mean your pet has a tumor, it's always best to have them checked out at DeVun Veterinary Medical Hospital.
