I have years of experience with dogs. I had a long haired chihuahua for 10 years who attacked everyone she didn't know. She was a very good watch dog. After she passed, I got a Pitbull. She was amazing with kids, and the sweetest lap dog I've ever known. I had another pitbull after she passed, and unfortunately our landlord evicted him. I have watched my aunt's golden retriever and German Shepard for years. I love every breed, and have no restrictions to which ones I'll watch, as long as they are good with children.
