I went through something similar with a previous co-worker. She has two small dogs that live outside. A couple years ago we have a severe freezing spell here in California. I had NO problem telling this woman that she shouldn't have these dogs at all and that she needed to either let them in the garage or get them a dog house with nice warm blankets. She said it was her husband that wouldn't let the dogs in the house or the garage.
But, to my surprise, she came back after the weekend and showed me pictures of a nice dog house her and her husband built for the dogs. And she put freshly washed blankets in there and the dogs LOVED it! I still wasn't happy that they lived outside, but at least I made progress with getting them a house.
Well, after she stopped working with me I found out (on Facebook) that they got ANOTHER dog! I asked her, bluntly, if this one was going to have to live outside too. Another surprise was her response. No, this one is living in the house. WHAT?!?! Why can this one live inside but not the other two? I don't get it. Oh well, I can only do so much.

My point is, maybe your daughter can make a bit of a difference for these animals. Of course she will be nicer about it than I was with my co-worker, but I have a feeling she can do it!
