It's so bizarre how often she has her mom's dog, Leo, at her house and vice versa often leaves Duke at her mom's house...sometimes for days at a time. It's really bad to constantly shift your pet's environment like that. Her latest explanation seems to be "oh my dog has asthma so [insert renovation thing]" but it's just an excuse for being a bad pet owner. She's been doing this for years. In reality, she does it because she either doesn't feel being around/dealing with her pet that day, or she's going on the millionth vacation of the year, etc.
Also she really needs to stop being so entitled/irresponsible and put a leash on the dogs. I don't care how cute she thinks her and her mom's dogs are, it's dangerous for both the dog and other people to do that (especially in a city).
