not just two weeks.. its been going on.. that is what I used to thinking too..but that is why i here to ask if this is normal?? my other yorkie, when she heating, she mate once or twice (stuck together) then she let him hit no more... but this other one, she letting him hit it all the time. The first time this female in heat, he was not able to hit it the right way, now that this is her 2nd heat, he learn how to hit her now he always wanting to hit her. When I let them out of kennel, he run right to her and jump on her. I turn around and they stuck together.. he is good learner..NO???
