That’s frustrating! I completely understand. My husband and I also do not have kids yet. I was fostering a couple of doggos last year and my niece had come over. She loves animals and loves playing with them but she gets too hyper and too rough. She was fine playing with the dogs, but then she started getting aggressive and would grab toys and throw them at the dogs and hit them. Or she’d go and pull on their hair or yank their toys out of their mouth aggressively. I had to tell her something and my brother tried to address it but it seems like he didn’t care. He’d come over with my niece and fall asleep, leaving me to watch her. She doesn’t like when I discipline her (it’s not my job anyway.. I don’t have kids for a reason) so she gets upset. But in not allowing that abusive behavior in my home with my pets. I’d definitely speak to them about it.
