I'm going to try my best to reply! I noticed you had a big fat zero by replies, so here goes....one little disclaimer...I'm not an expert in anything, so most of this is my opinion only!! It sounds like you have put tons of thought into getting a puppy so you are ahead of the game. The little male Yorkie does sound like he's a bit shy. My little boy yorkie did shake when he was nervous in the car, etc..when he was little. He rarely does this now (at 4 months). If you look at sites for tips on picking out puppies (which I'm sure you have) it does say to pick the friendly puppy, not feel sorry for the runt, etc and get a pity pick. You are better off health wise with a robust puppy. So, I know that doesn't really answer your question. Most likely, he's just nervous/scared, not very socialized yet. He would probably be fine once he got used to things.
I do have some concern about the amount of time little one will spend alone. Mine stay about 4 hours alone now, but when Scout was a little puppy my teenaged daughter was home with him full time. I wonder if anyone could help you out with puppy sitting? And he WILL cry the first few nights away from mom.
As for how much we spend a month on our Yorkies. That's hard to answer depending on health, etc....be prepared for the Vet check and shots right after getting him, and a good quality food is about $10.00/mo for mine (2)-small dogs don't take alot to feed. I wish you luck with whatever you decide to do, and keep us posted!! |
