My husband and I want to get a female companion for our male yorkie, our male yorkie is 1 year old and we would like to breed them to continue the line. I have done a ton of research, our dog is AKC registered. I just had a few questions,

1) I know a female should have her first litter between 1 1/2 to 3 years old, but after she has had her first litter, until what age is it safe for her to breed a litter

2) I know what age a male yorkie can start studding but is there an age when a male cannot stud anymore.

3) now my male puppy is 1 year old, and he weighs almost 5 lbs. should i try to get a companion for him that is about the same age or is it ok to get a female puppy, would he try to mount her if she was to young?
