I am hoping to start a dog walking and pet care business shortly. This is after cancer recovery it’s been a long struggle and it took me a year longer than I would have liked but I'm now fit and raring to start, but I want to get this right, I HAVE TO GET THIS RIGHT. I did a canine first aid course last year and an online dog training course although the later was primarily to help with the dog of a friend that I know look after full time and came to me with a few wee problems (also had some help from a behaviourist prior to doing the course) . I discovered I have an affinity with dogs which I never really appreciated before my cancer journey. Anyway, dog walking, I intend to walk no more than four at a time and want to be certain that I can safely and effectively procedure to introduce new dogs to walking together. I have walked three and four dogs together but they already knew each other but would appreciate how experienced professionals deal with introducing a new dog into the walking pack.
