I like dogs and own one. Boyfriend has 3 large dogs. One is a sweetheart and pleasure to own. One is generally unpleasant and very irritating but not a danger. The third is a proven livestock killer and serial biter. I allow it at my house when he comes at weekends, but very reluctantly as I have the general public around and livestock too. I insist it is muzzled and watched at all times when outdoors. BF tries to comply with this but is very laid back about the dog so I am very anxious when the dog is here. Today, I found he had let it out without a muzzle as he couldn't find one. My livestock was out and someone turned up at the gate. I am really upset. AIBU to say that he cannot move in while the dog is still around? He is normally thoughtful and considerate but seems to have a blank spot about this liability of a dog :(
