To tell you the truth, NO. Never a stranger. I walk my neighbors' dogs for them because both the parents are going through chemo. I wouldn't let anyone walk Niņo unless I absolutley needed to. I guess that is why no one ever called me to walk my dog when I had a buisiness. I would give my life for my dog, so no.
I would suggest a dog bathing business for the summer instead for family pets who's owners don't want to bathe thier own pets but don't want to take them to a groomers.
