I’m trying to better understand my shepherd’s behavior in our multi-dog household and would appreciate insight. Recently she went after my male Yorkie (not the first time) while all the dogs were gathered around my daughter eating on the couch. I’ve also noticed that during toy play, she will chase my golden retriever puppy and pressure him until he drops the toy, and now he avoids retrieving. She’s also become much more reactive over time (barking at birds, movement outside, etc.). Does this sound more like resource guarding, over-arousal, controlling behavior, or something else? What management changes would you immediately make in a house with multiple dogs and a large size difference? I’m especially looking for early warning signs/body language, what behaviors I may be unintentionally reinforcing, and how to safely manage interactions moving forward. Thank you!!
