I forgot to say in my initial reply, no, he is not neutered. He was originally my parents-in-law's dog. At about 4 months I noticed he was jumping on everyone, and it was a real free-for-all, and they thought it was the cutest thing. I insisted that as soon as he his the 80 llb mark they would change their tune, so I volunteered to take him to doggy school, but as he wasnėt my dog, I couldn't go get him neutered. I tried my best to convince them, but my mother-in-law just said "oh, poor thing", and I just struggled to keep my mouth shut.
At 9 months, (after 5 months of dog school and him showing to be a great student (for me) they decided that they couldn't keep him in their apartment. Without asking if I wanted him, my husband's mother gave him away
Luckily the family who took him realized that their dog wouldn't accept him, so they gave him back, and I took him.
We now live in a duplex with the in-laws, and the dog has sort of re-become everyone's pup.
Too much info to say he is not neutered, I would have liked to, but at 9 months the vet said it wouldn't help much anyway. I partially think that was bad advice, I think at that age it was hit or miss, but was is done is done, and at 6 years I don't think it would help anymore.
