About a week ago, I brought two 8-week-old kittens into my home. My 5-year-old, 40-pound mix-breed dog Benny has not responded well when I’ve introduced them. They’ve only had a few meetings, one of which was through a cat carrier (and Benny tried nipping at the kittens through the mesh) and once through a baby gate. During their most recent meeting through the baby gate, my dad was overly excited and was trembling/shaking. The meeting was brief, maybe 5 minutes, as I was concerned by his behavior. Now I’m wondering if I need to find the kittens a new home or if this is semi-normal behavior for a dog? Not sure what I need to do next. I live in a rural area so seeking in-person help from a trainer is not really an option for me. Thanks!
