Hello, I'm looking for some opinions as to how to approach a predicament. My older sister has a boyfriend, let's call him Nate. Nate is former military and ever since a motorcycle accident he's had a service dog. The dog is a trained attack and support dog. It is a very large dog as well. I do not like him one bit because he has charged me several time many of which have been while I'm just walking around the house. Nate says he has control of the dog but frequently is unable to stop the dog before he's got me cornered or is about to bite me. I know proper etiquette says I should invite Nate to the wedding. But that means the dog would be there as Nate will not go anywhere without the dog. I'm concerned about my safety and the safety of my guests at the wedding though especially since there will be children in attendance. I told my sister Nate could come but the dog could not and she's up in arms even though I tried explaining my concern. Any ideas for a happy compromise? Dog is in pic
