We just brought home an almost 10mo male Havanese 2 days ago. He is very sweet, but very quiet and shy. I suspect the pup was socialized with the other dogs, but not much with people. When we picked him up he was running and alert, but seemed more attached to the dogs than the breeder (wouldn't "come" to her when she called but would follow her larger dog).
We've been mainly leaving him alone to adjust. He's just starting to have any interest exploring...or walking much. He doesn't act really scared (no shaking, no growling or nipping, no accidents in the house, doesn't try to move away from us, is happy to sit near us, be pet), but seems really submissive. He's wary, but will eat chicken bits from our hands and I use that to get him to walk inside after being out (when he's done going potty, he comes with paws on the back door, but will tend to step back when we open it). In the evening I'll put him in my lap or next to us and he relaxes and seems content. But otherwise, he's not walking around much when he's indoors. I have his crate in an exercise pen in the living room. He'll come out of his crate to lay on the carpet, but that's about it.
Any experience with bringing a shy, older pup home? Any advice? I appreciate the stress and change he's experiencing, but will he warm up eventually? We have kids, so I am hoping for a dog that will eventually be more playful. The kids are being very good and patient, leaving him alone.
I just don't know if this is "normal" or an indicator we'll have trouble down the line.
Advice and encouragement appreciated!
