Aggressive Yorkshire Terrier
I have 4 dogs, 3 Yorkshire Terriers and 1 Jack Russell. 2 of the terriers had a puppy who is now 4 years old.
About 18 months ago is when the aggression first started. The youngest "George" will randomly and quickly attack "Charlie" (his dad) for no reason at all, it seems to happen when one of the dogs or human walks into the room he's in. He will lock his teeth round Charlie's ear and won't let go.
We have resorted to putting George in a cage now which has become his permanent residents, but this is not solving the problem as he attacks as soon as you take him out. He rarely goes for Alfie the jack Russell as he is bigger and stronger but as time goes on he is becoming more confident and is going for him. He doesn't go for darcy (the female) at all.
All makes have had the snip and darcy has been spaded too. We have put a muzzle on him but that doesn't stop him attacking, it just makes the jack Russell attack him in defence of the other dogs.
We are at a loss with what to do and feel like the only solution is to give him up, which would be heart breaking as aside from these random attacks, he is a lovely playful dog. I hope you can make ends or tails of that description.
Can you please suggest something we can do?
It feels like drastic measures are needed
