I've posted a bit about my rehomed nervous dog reactive chi. I'm going away at Easter (rescue knew this) and said I'd be sorting out home boarding/kennels whatever suits them best. Chi reacts to other dogs with barking and jumping around. Not been around other dogs for any length of time to know whether she eventually settles but I'm guessing even with home boarding there'll be other dogs there which will be nerve wracking for her.
How do other people have their nervous dogs cared for? In future, Im happy to do dog friendly UK hols, but this holiday was prebooked (and as I said I told rescue this)
