UPDATE:
So far he is doing OK. He is not neutered as we were told. His teeth are in horrible shape and he does have a slight heart murmur. The biggest issue right now is the marking. Of course, the poor guy is very confused and appears to have some dementia but I think as he decompresses from all of this happening and he will settle down. His bloodwork was not bad and of course, most of it was due to his nasty teeth. He is not a dog you would do a dental on or even neuter at this time so he is wearing a belly band. Loves affection and loves to just chill. It just breaks your heart. He just wants to go “home”.
One day at a time
