Can my dog be rehabilitated after unexpectedly biting me multiple times, or is it too late?
Full Question:
Dear Cindy, I was recently bitten by my 3yr old intact male Doberman. It was very unexpected, he was laying on the floor & I sat by him to touch his back leg (I noticed stiffness) he lunged forward, attacked; he bit me in multiple places and only stopped when pulled away by another person, luckily I didn't need stitches. I know dogs can lash out when in pain, maybe this is a naive assumption , I thought in those instances it would be one time bite and release situation (he seemed to be in a blackout rage). Prior, he has been very good at being handled & never once shown aggression or bitten anyone. He has severe reactivity towards cats, some dogs (recently he has growled at our other dogs), barking at guests at the door and in the days prior to the incident his negative behaviors had been escalating. He has never been professionally trained. I am now in contact with vet & trainer. I am unsure how to move forward, or if we’ve passed the point of no return but I would like to try. 
Cindy's Answer:
It's crucial to take this situation seriously, especially given the bite history and your dog's escalating behavior. Pain can definitely trigger aggressive reactions, so I would work with a vet to rule that out first. It is fairly common for male dogs reaching 3 years of age to become more territorial and aggressive than they were previously. Working with a professional trainer is essential, particularly one experienced in aggression and reactivity. Ensure they observe your dog in person to develop a tailored training plan.
In the meantime, manage your dog's environment to prevent further incidents. Consider using a muzzle when necessary, especially during interactions where you may need to assess his comfort levels. A polymer-coated muzzle can be a good option for safety. Keep your dog on a leash or crate him when around guests or situations that might provoke him, and avoid handling any sensitive areas until you have a better understanding of his triggers and can address them effectively.
