If your daughter moves out before then, why couldn’t you ask her to come back & stay at your house for the week? Maybe offer to pay her a portion of what it would cost to kennel the dogs. Make the condition the BF could visit her, but not stay there. I would hope she’d be willing to help her mother out & agree to him not staying for 1 week. She could go “visit” him at her apartment once or twice during the week if she absolutely must. Then come back & stay overnight with the dogs.
