I have been around dogs most of my life. Our family has owned small dogs as well as large dogs weighing over 75 pounds. I currently own a rescue dog who is the most friendly 75 lb. pit/boxer mix you will meet. I also have an indoor/outdoor cat who gets along with dogs. However, if your dog has never encountered a cat creature, no worries! My cat will stay away from a new dog in the house. I have watched active dogs as well as very mellow dogs. I will sleep with small cuddly dogs if that is what makes them comfortable. I love taking my dog to the dog park. I work close to home allowing me to be home for lunch to let them out. I look forward to meeting your dog!
