I'm afraid my GSD is getting jealous of my other dog
The last two times I've let my 51/2 month old GSD male and my 1 year old Labradoodle female together, there has been some pretty rough play. I'm pretty sure it's not all play, he seems to be jealous of me spending time with her. I feel like, in many ways, I'm having to go back to square 1 with some of his training that he had seemed to have down really good, since he's hit the "adolescent stage"He has some separation anxiery which has improved, but he is also really bad with jumping on people, which I've never allowed him to do, and sometimes runs away when I call, even though he used to have a pretty solid recall.
But anyway, I am concerned, as I really want to keep both my dogs, but can't have them not getting along. One piece of the puzzle may be that she recently came into her first heat, and he has very aroused since then. I have successfully prevented any mounting attempts, but I think that may be part of the aggression. (I want to use him as a stud in the future, so neutering is not an option) I am always with them when they are together, and stop any play that gets too rough, or has if dog is no longer having fun, and if there's any growling (there was once, over a bone) play time is over. And I try to spend equal time with both of them, especially when they're together, to show them they don't have to keep the other one away in order to be with me.
I would really appreciate any tips or suggestions. Thanks!
