You’re doing the right thing.

Is Mr. P going to be equally enforcing the consistent training, doing the walks and cleaning the poo, taking it to the vet, paying for the costs? Responsibility for a pet tends to fall mostly on mum and all of the effort, cleaning and replacing chewed items also goes up with a baby animal.

Hopefully there’s a better situation in future and you get to wholeheartedly say yes to a puppy.
