I don't think it's a big deal tbh. Like
@luciejaneg said, lots of people crate their dogs at night and it's (usually and hopefullly!) not as some sort of punishment. A lot of dogs literally just sleep in their beds all night. Our dog sleeps in the kitchen at night and it doesn't mean she's not thought of as a member of the family!
I've only ever seen evidence of Megan treating her dogs well and being loving towards them/taking them for walks etc so I'm not going to assume she isn't a good dog owner.
