I agree that she may be getting ready to go into heat, and along with the excitement could be triggering the aggressive behavior in your other female, and she is targeting her.
If you will be using her for breeding, getting her spayed is not an option. You will need to separate her from the other dogs, especially if your males are not neutered.
Address the cause of the excitement. I believe you mentioned taking them out and leashes being a cause? Desensitize them to the leashes. Start keeping the leash out and in their site at all times, so that it starts to mean nothing to them. I have my clients start by actually hanging the leash over their shoulders, wearing the leash around their waists, and keeping them on their bodies every day all day. Then I have my clients hang the leash over different pieces of furniture, on different door knobs, on the floor by different doors, chaning places so the dog gets used to seeing the leash in many places. Another exercise I do is have the dog sit and put the leash on then praise and take it off then praise. Repeat a few times without going outside.
Once the dogs stop seeing the leash as something to go nuts over, putting the leash on to go for a walk will no longer be a chaotic experience. And if you practice having them sit when you put the leash on and take it off, they will be calm during that process as well.
Hope this helps with the leash excitement and calms that trigger! |
