The first time my sister came to visit, via plane, after I got my dog, pupper growled at her and wouldn’t go near her for the first day. Next visit was by car (two day drive)and pupper LOVED my sister. They snuggled and played and none of us could figure out why the change. We thought maybe the scent of my sisters cat had lingered on her clothes, making that first visit a rough one. Whereas when she came by car, the scent had had time to wear off. Well that was partially true…
Fast forward about six months when I went north to visit my family. My sister walked into my parents’ house and pupper ran to greet my sister. Stopped dead in her tracks and started growling and barking. Hackles raised, full protection mode. My sisters husband had just walked in behind her.
My precious puppy wanted NOTHING to do with him. She barked, growled, ran away, and sat between him and my sister. Y'all my dog had spent maybe a weekend a half around my sister but protected her like this was her flesh and blood.
Eventually, my sister filed for divorce on grounds of “Extreme and repeated mental, emotional, and sexual abuse.” Divorce was final in less than a month because her claims were substantiated.
Trust the dog, honey. They KNOW.
