Tibetan Terrier Drinking Heavily With Painful Tail Bumps and High Calcium
no cancerous cells shown there. I believe it looks like he has an adrenalin gland disease. What should I do if his pain medicine and antibiotics do no obvious relief to his sufferance?
Heavy drinking and urination with high blood calcium is important to follow up. High calcium can damage the kidneys and is caused by certain cancers (especially lymphoma and anal sac cancer), parathyroid disease, kidney disease, Addison's disease, vitamin D poisoning or some fungal infections. Cushing's can also cause heavy thirst and skin infections.
Ask your vet to recheck the calcium (ideally ionized calcium) and to look for its cause, and to culture the tail infection, including for fungi, if antibiotics aren't helping. Tell them how painful he is so pain relief can be adjusted.
