[zekie's mom]

Actually I have four questions:
1. Zeke is 15 weeks old and so far no sign of testicles. When should they show up?
2. When should his hair be long enough for a first grooming? It seems to be growing very slow, and I am not complaining. He has very nice fur. I was just wondering.
3. Do all Yorkie's have trouble with double teeth, and what happens if you let them take care of themselves?
4. I just started using treats. I give him one in the morning after he gets his eyes washed out as I was having trouble with this. Then he gets one in the evening around 7:30 just for the heck of it. In between, I sometimes give him some Cherrios while I train him to sit, etc. Problem is, now he begs for treats all the time. I do not give in and give them to him, but it is very annoying. Does anyone have any suggeestions on how to curb the begging?
