Darker dog on right is the aggressor.
We have two rescue dogs, adopted three months between each other. Our first rescue, who is also a very anxious dog, has been attempting to attack our other dog nonstop for a little over a month now. Usually, the attacking dog would chase our other one down at the dog park, in our backyard, or living room, and our 2nd dog would just submit, and then move on. But, he is now fighting back...hence, the fights have become quite dangerous and scary. We have been keeping them both separate, unless we are both controlling them by leash...still, lunging, attack mode, out of control behavior ensues.
We have already had one emergency vet run for stitches under an eye (of the aggressor), after an attack. Is there any hope that we can get these dogs to get along, at least so they can, once again, hang out together without attempting to kill each other? We used to be able to sleep with both of them, have them ride together in our vehicles, go on walks together right next to each other...they were always together without fighting. (With exception of the controlling behavior when entering the dog park).
