Would it be possible to put a fence just around the dog run? To keep people back?
I will occasionally leave one or two of our Bs in the back yard if the weather is great, and I will only be gone for less than an hour or so….but we do have a privacy fence, and live in the country.
I would be far to afraid to leave a dog exposed to any old person walking by in the city (or in the country). After having worked in a zoo for over ten years, I have seen to many people do too many stupid things to think that they will use common sense around animals. I don't want to subject my beloved pets to other people
Rocky will be fine with only supervised outside time. And I wouldn't let one unobserved bite incident change the way you feel about your dog. He is still the same dog Dogs will bite if pushed too far, it doesn't make any given dog a nasty dog.
Sorry you had to go through this....
