Should I confront my sister in law about slapping her dog?

Violence against animals is very concerning.
Can you talk to your brother instead, if it’s his wife itmay be best. He would likely know if she has anger issues or needs help.

Your sil is NOT going to appreciate your butting in & that might make it worse for the dog. I agree that maybe you need to talk to your bro & let him handle it…keeping you OUT of it!!!

My brother said he agrees with slapping dogs when they’re misbehaving. What do I do now?

I’m not going to read the details of your question because they don’t matter. Fuck yeah, you should confront her. Nobody should be hit – especially dogs.

BIG MISTAKE!!!

And what would you give them when they don’t obey?

How does your mom feel about slapping dogs?

If she agrees with you, perhaps you could mention it to her.

First, what was the dog doing before it got slapped, what breed is it and how old is it? The reason I ask is that some dogs that tend to be aggressive when they get overly excited. She may have done this to get him to focus and not lose his mind. You also mention it wasn’t a hard slap. Just made a sound. Well, I pat my dog and it can make a sound, and it’s not an aggressive hit. So was it a slap or a pat? Of course when I pat my dog it’s not in her face but I’ve seen people do this to calm their dogs. This often comes from people who don’t know how to train their dog.
Then of course you could also read up and google how to handle a dog when it is excited and when you speak to your sister-in-law mention that. Also if it is still in the teen or younger years they are easily excited but also easier to train. If the dog has some treats work with it on staying still and ignoring the treat till you say he can have it. There are some great youtube videos you can go through. If you manage to get it to listen, with this then pass along the info to your sil. Just tell her you wanted to have fun with her dog and see if he would do better with some training. If the dog enjoyed it pass it along. This way you don’t seem confrontational and she may take your suggestions. Talk about what a good boy or girl the dog was during training and how the trainers said slapping a dog can make it aggressive or fearful.

Not now. When she did it you might have said that that seemed like a bit much. But that moment is gone now.

My mom said that she doesn’t agree with slapping dogs, but she says she’s not going to say anything.

Unfortunately there’s not much you can do unless it’s abuse, which one instance doesn’t prove.
The cane corso abuse in Louisiana would be a good topic to discuss as a family, see what they say about it.

Since your brother agrees with her & won’t talk with her & your mom won’t talk with her, any chance that the slap wasn’t as bad as you’re thinking about it now??? From the way you described it, the hit sounded more like a tap to me!!! IF she hits the dog in front of you again, confront her then & there instead of waiting to ask Fluther what you should do.

Scary, since if a person is cruel to animals what do they do when they have childen.
Perhaps mail information addressed to her about how to handle pets and the incorrect way of slapping a pet is not kosher. Or a phamplet convering that topic.

Yes you should. You shouldn’t hit your pets.
