The bitch has a one litter naturally, I usually do progesterones but didn't this time around,my bad. I never collected this boy before and he seems to back off if I go too close when he mounts her. I may try to do an AI first though, but not sure he will allow. He sired a litter about a month prior so I'm pretty sure he is ok. He was getting Rimadyl at the time for an ortho injury (not severe just a strain) so not sure if that had something to do with it. He was very eager and didn't give up, just never got a tie.
