Hi hrhbabushka.....
What breed and/or size is your dog?
When you purchase a crate, be sure to get a very heavy sturdy crate.... the kind that is open (not solid walls), so that the dog can see around the room..... your dog might jump and wiggle, while inside the crate, to the point of actually moving the crate around the room.....
Also, you might consider hiring a "baby-sitter"..... a local teenager who would like to earn a few extra dollars.... to stay with your dog while you go out.....
Do you have "Doggie-Daycare" centers in Scotland? Unfortunately, they are usually only open during the daytime business-week hours..... However, they are an excellent resource for dogs with separation anxiety problems....
I hope you can find a solution that allows this dog to remain with you.... You sound like a responsible caring pet owner.....
