Grandparents have a dog which is diagnosed with anxiety as it's wets itself possibly party due to lack of exercise. We are going to visit and they are quite happy to let there other grandchild crawl all over it. How do I explain that I am not happy for my child to do this? I come from an animal loving family so understand the dog is their baby but I do not want my child to be at risk of being bitten. Baby is at rolling stage and will roll towards the dog and is to young to understand not to go near it.
