I suggest you go to Debbie Jensen's website, very good infor on breeding.

It is likely your boy will mark more especially around strange houses and also when a female is in your house.

If he doesn't hump now, there is a likelihood that this behaviour will increase; again especially around females.

Some dogs need assistance with the actual breeding, you will need another person to know what they are doing here.

Both dogs should be checked for Brucellosis prior to breeding!

And finally if you don't want to breed your dog don't! It truly should not be done on someone elses' whim or desire. You are at least ethically responsible if not contractually responsible for the litter borne, and unless you know the lines well and have done all the requisite health testing, do you really want to risk puppies being born with genetic health problems; of which Yorkies are prone to more than a few of them?

Finally I would not stud my dog out to just any-one, nor would I do so without a stud contract. And the first thing to check in your documentation is do you have full registration, or a limited one? Limited one means you are not allowed to breed this dog! If your breeder has given you full rights for breeding, then the first person I would go to for advice on this particular situation is your breeder.
