Q: Why has my dog lost his appetite and has started shivering?

Original Question: "I have a Terrier mix who is 12 years old and lately has had a full loss of appetite and shivers. I have taken him to the vet twice to have blood work done and all of the results were normal. He seems to be wasting away; do you have any idea of what could be wrong? Please help." - Sandra

Hi Sandra,

I'm glad to hear that you have had your dog checked out by your veterinarian. It's unfortunate that the blood tests are normal in that we don't have a clear picture of what's going on but it's good that we have eliminated some possibilities. Some conditions unfortunately cannot be diagnosed with a physical exam and blood tests so further testing such as radiographs or an ultrasound may be needed. A few possibilities to talk with your veterinarian about would be inflammatory bowel disease or cancer.

I hope this helps!
