Hi all. My lovely cockapoo (nearly two and I absolutely promise not from a puppy farm) is aggressive towards strangers coming into the house and/or delivery drivers etc.
If it's somebody he knows, we're absolutely fine. If not, we are definitely not. I have no doubt that he is not just warning people - he would attack if given the opportunity.
In all other circumstances he is great. No problems out and about, no problems off the lead in the park, or with other dogs. It's just if someone he doesn't know comes into an enclosed space - and in fact, that doesn't have to be our house. It's happened when visiting others although he seems fine with some people and not others.
Our next step is to muzzle him whenever there could be a risk which is really devastating but necessary for everybody's safety. But how on earth do we train him out of this? Is it possible? If so, how?
I am obviously really sorry it has come to this - I do blame myself though I do wonder whether it's because of course nobody has been coming in and out during lockdown so he's really not used to it. For background, he's also being quite teenage at the moment - a bit defiant, a bit of a dick, at times. He's not been neutered yet - also a lockdown thing, but will be at the end of June.
Any thoughts/advice?
