Just as the title says: I have a 1 1/2 year old male that I let out under the car port to run around and get some exercise. Well, I also kept one of the kits from the last litter and I figured I would start letting him, (I'm 99.9% sure its a him, he has something that starts to stick out when I push on his private parts,) run under the car port now. Jax (1 1/2 year old,) comes up to him and wants to hump him. He already got his face once and really doesn't care if he gets front or back. Is this normal? Is Jax just trying to establish dominance? Should I let him continue so they can get it over with or should I stop it?
