We're moving to Germany soon because of my husband's job and are having a dilemma about what's best for our dog. He's a 10-year-old Lab/collie cross, who's always been a bit highly strung. As we've started packing, he's become quite anxious (we've moved around a lot while we've had him). The only way for us to get across to Germany, because of where we live and where we are moving to, is on the overnight ferry. This involves the dogs being crated in a kind of holding area on the ferry down on the car deck overnight and you're not allowed to go down and let them out or anything while the ferry is moving.
I'm really worried about this because he's started to get anxious when, for example, he got himself locked in the bathroom one day while we were out and nearly clawed the door down to try to get out. He does have a crate of his own but it's never shut and I don't know how he would cope with being locked in, other dogs howling, the odd smells and noises and so on.
We do have the option of leaving him with DHs parents - he's stayed with them before, they've got a dog who he gets on well with and there's someone at home most of the time so he wouldn't be alone too much.
What would be best for him? He's already got a pet passport so it's no drama for us to take him with us, but I'm incredibly concerned about the ferry journey and the crating. Any advice would be welcome.
