Hello. My name isXXXXX will be happy to help you. If he is not itching, he most likely has an endocrine (hormonal) cause to his hair loss. Hypothyroidism
would be the primary concern. If he is drinking and urinating
a lot, then an adrenal gland problem called Cushing's disease is possible. Some dogs suffer from a condition called seasonal flank alopecia
, but that usually occurs just in front of the rear limbs. A skin mite infection called Demodex is possible. You typically see this in puppies, but older dogs can get it with immune system issues, which can be caused by any of those issues noted above. I would have your vet do a skin scraping to look for the mite and run a full senior comprehensive blood work (should include a thyroid panel) to see if they can't find an underlying hormonal cause of this. If he was itchy, I would be more concerned about an allergy (food, environmental and flea), but that doesn't seem to be the case. Ringworm
is possible but less likely. A ringworm culture may be a good idea to be on the safe side anyway. Please let me know if you have any other questions or concerns. Hope this helps.
