I agree. I was just thinking a bit ago that while he's got a good temperment that it doesn't seem like he's been loved and snuggled and just played with like a dog should be. I told Cayden that I think in a week or two he will be more comfortable and relaxed and "come out of his shell". He just needs time to learn to trust and feel comfortable here.
I was wondering about his backside as well, especially with his age.
If he doesn't become a snuggler, don't stress over it. Our dog was 8 months old when we adopted him from Michigan Humane Society. He was feral...a runner...no rules, no respect, and a firm no touch policy. He was not the best candidate for a dog to bring home for two kids.
He is 9 now. He will still run off whenever he can slip through the door. He still will not snuggle. He will sneak up on beds and rumple pillows, and he loves back scratches. But he will never kiss and never snuggle and turns away if we "invade his space" too much. We will not bring in a new dog while he is alive, because we don't want him to impart his bad habits that we cannot break, but we love him nonetheless.
A family came by to take a look at the turkeys, and their little girl ran up and kissed his face and ears. Surprise...he didn't move away, he offered a paw, he laid on his side and almost rolled over. I just do not understand that dog. White Castles, Pupperoni, rides and walks he will debase himself for. Other than that, he is usually aloof.
