Hi, I am new to dog breeding and need some help/advice. I have one male Boston terrier and a female Boston terrier, my female is on day 11 of her heat but my male doesn’t seem quite interested, he whines and sometimes goes to jump on her back to hump her. My female is ready because she keeps sticking her self in his face and she arches her back, but he only really licks and walks away. When he does hump her it’s only for a couple of seconds before he gets off. Any advice would be helpful really. They are both around the same age F 2, M 1 1/2.
