We are sending mine to my parents. They are used to having them and the dogs love going there, so they will have them for a week or so.
Can you not arrange for a friend to have your dog for a night or two? Or someone to come let it out for you a few times? Is there no one at all who can help?
Worse comes to worse, arrange a dog sitter or put them into a local kennel for a few days. Yes it will cost, but we choose to have pets so if need be we have to be prepared to foot the odd bill if we want to go away or we don't want them around for whateve reason. Its not our pets fault, its just how it is, and I like to try to make sure I do whats best by them aswell
If my parents were not having ours, I'd leave them at home and hubby would nip back to let them out and walk them, and if we were away overnight they'd be fine for 8 hours. I'd also ask a friend to maybe come stay if I felt they needed it.
I don't want to exclude our pets and would be happy if they stayed here, once I am home with baby but my parents offered and are happy to have them, so its ok. Hubby is great with my menagerie and happily takes on board walking, feeding and cleaning if I cannot. He'll be seeing to the chickens for a week or two once Baby is here.
