I don't want my grandma around my service dog
Why don't you want your grandma around your dog ?
I want my dog to only be with me and no one else can have them! I don't like my grandma touching my dog.
You shouldn't do that to your grandma. She loves dogs and just wants to pet it. Don't exclude her.
No! My dog needs to like me and only me!
The dog is yours and nobody is trying to steal to it from you so no need to make a big deal about it. If your grandma likes your dog, you should let her pet it. There's no harm in it.
