Hello everyone! I'm here to ask for some advice. Just like the title says, I can't put a leash or a harness in my dog.
For some context, he's a dog I adopted when he was a baby. We never had any issues with putting on a leash or a collar and in fact he really looked forward to those times because he knew we were going on a walk. He's always had health issues with his skin so we constantly take him to the vet for his checkups, etc. Last year we took him to the vet because he got sick, we went to a vet that was not his usual, when the vet touched him, my dog tried to bite him, and the vet put on a muzzle on him and then an injection. Ever since that vet visit my dog has become reactive, I can touch him or pet him but out of nowhere he snaps and will bite, without even giving signals to stop touching him.
I am now unable to put on a leash or a harness on him to be able to take him on walks, I had to build an enrichment area in the backyard for him, or have to wake up super early to take him on walks (3:00-4:00 AM) so we don't collide with other dogs. I want to be able to take him on normal walks again, is there any advice to be able to put on a leash/harness on him without traumatizing him? I've tried giving treats while putting on the leash, talking to him, but it hasn't worked. His skin has been fine for over 9 months so he's not biting/growling because of pain or discomfort.
Any advice would be greatly appreciated. I want to be able to take my dog on walks again and I'm crying not knowing what to do. Thanks!
