I have owned and raised bull terriers for the last 15 years. I have taken care of many dogs at once for a licensed dog kennel. I believe good dog behavior is all about how they are raised and treated. I own one bull terrier now who is 10 years old. She is sweet and gentle. My cat is about 4 years old. I have had her just shy of one year. She had a couple of owners before me and I think she wasn’t treated very well by someone before me. It took her a few months to trust me. Now she purrs on my lap all the time. On her terms of course but that’s okay.She is an inside cat, never goes out. I never leave my dog unattended outside and never let her run loose outside. I have a portion of my backyard fenced in. My sliding door and the side door of my home opens up to it. It is a nice area for small dogs and/or calm medium sized dogs. But it is not appropriate for large dogs that will jump on it. My dog Olive is around 55 lbs but she is approaching 11 years old now. Perfect for her as she just putters around the yard. She likes laying in the grass especially in the sun. Will love you dogs and cats as my own!
