Oh for goodness sake, I am sorry, but if your relative had had a dog, they obviously like dogs, so I can't understand why they would object to you turning up with your own dog (a dog which is the same breed as their own dog no less). I can't fathom why they would object (if they didn't like dogs, well, fair enough, but they had one of their own previously, so were obviously dog-lovers). Sorry, but just seems weird to me! If you are a dog-lover, why would you possibly be annoyed when another dog-lover arrives at your house with their dog?!!!!! As, a dog-lover myself, I'd be thrilled!!
