Okay, so I have a male, Cooper, and a female, Cali. Yorkshire Terriers... Cooper is 10 mo and Cali is 8 mo. The come from 2 completely different lines, and it is my hope to breed them eventually. Cooper has gotten to that stage where he wants to hump everything. And I don't want to discourage him, because I want him to breed in the future... He will try to hump Cali, but she doesn't like it so much and will wrestle him off of her. So instead, he will hump anything, from shoes to bunched up blankets to pillows to his doggy bed... The weird part is while he is humping the object, Cali will mount and hump him! Is this normal? I have enver seen this before... Does anyone know why she does this?
