15 month old female black and tan dog (Sturgis)

I'm looking to rehome my sweet girl. I hate to because she is a great dog. She just plays too rough with my smaller dog who recently had a serious spinal injury. She's almost 15 months old, smart and learns fast. Knows all basic commands, is great with kids and other dogs. She would do great on a farm or with someone with a big yard. Free with her toys and any food I have left.
