I think it’s a bit unfair to call them scum, they adopted the dog in the first place and then their circumstances changed. You dont know what conversations they’ve had to come to the decision they have, and perhaps they thought it better, for their own reasons, to say they’re allergic than to say they’re expecting a baby.
My niece, a GP, has two Bosnian rescue dogs who have changed her life completely...for the worse. She’s had them two years, gone through three dog trainers, and they’re no better than they were when she got them. They’re aggressive, big dogs and none of the family or her friends will go to her house now. She and her husband are building a secure run outside for them so they can be put there and allow people to visit again. They’re also looking into taking out insurance should they escape, attack and seriously injure someone.
Myself and the rest of the family think she’s nuts and should have them put down but she’s committed to them.
What Im trying to say is that everyone has their own reasons for doing what they do, regardless of what anyone else thinks.
