Boundary Question.

I just listened to episode 12 on boundaries. I was hoping to get a little guidance on how to set a boundary in a situation I find myself in a lot.

The situation I need help setting a boundary is with my mother in law. Every time she comes to my house she yells at my dog. He gets excited when people come over and he’ll run up to them and sometimes jump. It’s something we are trying to train him on. People are usually very understanding but she isn’t. She will yell at him long before he is even near her. Which I get she’s not a dog person. It just sets the tone and mood for our home and for our evening.

I’m stuck on how to approach this which is why I haven’t. She’s not the easiest person to talk to but I hate feeling such negative emotions every time they come over.
