I used to run my own dog walking buisness with a freind started when I was hmm like 11 and my freind was..like 9 and we went to people on our block we went to every single house that had dogs and we had alot of dogs for walking I dont know why people trusted us with their dogs but I've been walking only one of the same dgs for about 4 years now it's like shes my own dog she comes in my house and everything..BUT thats after I got to know the people alot and stuff and I would NEVER trust some stranger with my dogs...the people whos dog I walk the one who I knew for 4 years they had another dog that I knew for that amount of time as well great dog they were rehoming her cause they couldnt bring her to work with them cause she was too big and couldnt find a cheap babysiter for her so they put her to sleep!!! After that I stopped walking the dogs and so obviously they didint care who had their dogs...
