Diarrhea or changes in bathroom habits
Occasional diarrhea usually isn’t a sign of cancer in dogs, says Dr. Rocha, but if it persists or gets worse, get your dog to the vet. Constantly begging to go out to go to the bathroom, difficulty peeing/moving bowels, vomiting or blood in the urine or stool are also potential dog cancer symptoms, according to PetMD.com.
