I don't want my dog to stay at my inlaws whilst we are on holiday
Why not let your dog stay there?
I grew up in a culture where animals are not allowed in the house.
It's understandable that you would want your dog to be taken care of while you're off on vacation. If you don't feel comfortable with leaving your pet at their house have you thought about a bordering location?
Are you a veterinarian? Fuck you, I'm gonna make my dog suffer.
It is normal to board animals when you go on vacation. There are quite a few options to board them in fact. You just need to make sure that your animals are taken care of when you are on vacation.
