Woman Lets Sister Move In, But Not Her Dog

OP and her husband live with their three kids. Her sister, who is 19, has an infant son of her own as well as a dog. OP has no problem with her sister and nephew living with them since their parents are not supportive, but she has an issue with the dog moving in.

OP does not want to have a dog in her house, as she has cats and worries about the dog's aggression. She also doesn't want to end up taking care of the dog, especially since the sister isn't financially stable and might rely on OP for dog supplies.

OP, who believes her sister should never have gotten the dog to begin with, finally said that her sister could only stay if she gets rid of the dog. The sister, of course, is upset by this and told OP that she's being cruel. Now, OP is wondering if she crossed a line.

Users agree that, for the sister, it's a tough situation, but she also needs to respect that OP doesn't want a dog in her house. The sister needs to prioritize taking care of her son over the dog, at least for now.

It seems that the sister isn't open to compromise, either. The dog could stay with another relative for the time being, but the sister refuses to separate the dog and her son.

For the child's sake as well as the dog's, the sister needs to decide what's most important. At the end of the day, OP shouldn't have to welcome a dog in her home if she doesn't want to.
