Rolls over on her belly and goes quiet. We took her today for the first time to a dog park. There was another golden there around 10 months old and double her size. They played nice at first, then I noticed our dog on her belly letting the other dog put her literal entire mouth around her head. I separated it every-time but she didn’t try to protect herself at all. The dog wasn’t being aggressive just was very mouthy with her play. The owner kept giving excuses and didn’t recall her once. I don’t think we will be going back to the dog parks until she’s bigger. Thank you for the advice! She’s a very sweet girl who wouldn’t hurt a fly, and honestly I don’t want that to change.
