Our very much beloved and lovely ILs live quite a bit away, and so when they visit, stay over. They have also a couple of times pet sat for us. We are really really grateful to them for this BUT. They have started allowing their cocker up on our furniture. This includes beds, sofas, velvet covered armchairs and they now expect her to sit with us at the dining table.
She has her own armchair in their house, but as far as I know, sleeps in her basket at home.
I could rant, and give you all the details, but it's probably not necessary. Would you expect to us to turn a blind eye to your dog being on the furniture, when we have expressly said, several times, that we think the dog should remain on the floor (as ours does, quite happily, apart from the odd lean against us).
Help, I just want to decide whether to be more firm with them, or just take a deep breath, and be grateful to have such generally fabulous ILs.
