I have no "professional " experience but have had dogs my whole life. At one point the family had 4 dogs and one cat. Space was limited and you had to pay attention to where you walked.Add 4 kids to the mix and the beds got crowded. I am retired so this will help me fill out my day. And I will get to be with dogs all day. I will be with my best friends get excersize and get paid for it. In my view that equals win,win and win. I love all types of dogs and all breeds. I had a gold retriever that was a sopping one hundred pounds. And like most big dogs was a sweet heart. Sat on every ones lap. I will watch,play, and walk them like the dogs are mine. Regards, Brad B
