I know you guys are not vets, but any knowledge, hunch or experience will help me at this point.
Basically, it all started about 2-3 years ago. My dog Coco (neutered, then 7, lhasa mix) started to salivate excessively when left alone. We assumed it was just anxiety.
Then one day we found him in a pool of blood, after he had licked his penis for a while. It had come from there, it was swollen thick. We thought he had bitten himself or something. We rushed him to the vet, and they found NOTHING wrong. Aside from the bleeding he was "fine", the swelling subsided.
Between then and now, it has happened a few times more, but has since stopped salivating excessively.
We have taken him to two more vets to check this problem out, because bleeding from genitals is not normal...they have run urine tests, blood tests, prostate exam, physicals, feces exam...they checked some lumps he has grown, but they said it was just fatty tissue....you name it....other than a few crystals in his urine...they cannot find anything wrong with him! They just prescribe him antidepressants! They say he is just anxious/depressed.
My baby, now 9, is getting worse...we keep him from licking himself with an E-collar, but now licks the floor, and he isolates himself at least once a day for a while. He won't eat, drink, pants, and he is gets desperate to either be alone outside or the garage, away from us. He is lethargic and shivers. I can tell something hurts him! Everyday this happens.
Then he goes back to normal and eats.
He doesnt even chew his rawhide anymore (he loves it, but does not chew it like before)
We are taking him to another vet next week, but I am really at a loss....what else can I request for them to test? Any experiences? What could it be?
