DD has got a wonderful relationship with her grandparents and stays with them regularly in school holidays. She is a naturally timid child and dislikes being around loud noises, sudden moves or boisterous behaviour. She is a very slight 11 year old. She has a strong fear of dogs. About a month ago with no real warning they got a rescue dog (in fact previously the grandparents had said it was unfair to get a pet as they may not be around long enough to care for it - both in 70's and heavy smokers). Not any old dog but a Cane Corso or Italian Mastiff. Comedically large puppy (18 months) and super exuberant. DD was anxious about going down there but we all reassured her it was friendly and engineered first meeting as calmly as possible and on neutral territory. Day 1 went fine apparently. Day 2 she rang me in hysterics asking to come home and almost screaming with terror. When I collected her she was still trembling. I made a big show of the dog (I am not a fan but am certainly not scared of them) and how friendly he was but she was not having any of it. The dog jumped up at me several times and it is strong. On reading up about the breed it seems most Cane Corsos are "too much dog" for the average household. He is only going to get bigger and stronger although as he matures i assume he will calm down. Anyway, my question is this: AIBU to not insist she goes back there, at least for now. She is adamant she does not want to see the dog again and probably does not quite realise this means not staying with her grandparents. I think i need the dust to settle for the moment but i am worried DD will stick to her guns indefinitely . I am still a little staggered that they bought a dog knowing just how strongly their DGD felt about them but its their house and their choice and I can't possibly ask them to take the dog back. Any advice welcome. Especially on how to manage the dog and DD's relationship moving forward. I am a cat person so have no idea!
