Looking For A Pet Sitter For 1 Dog In Berkley

My sister's dog Lilly is a brown medium size mixed breed. She is 10 years old and extremely affectionate and loving. She has a bad leg with some arthritis so too much walking or running can irritate her joints. My sister has a new job that keeps her from home longer hours than usual and Lilly would love just a walk around the block and some pets a day or two out of the week. She's not super great with leash training as she is very excited for walks because it's not very often. So she pulls but it's nothing crazy if you're willing to do a brisk walk. Her whole butt wags with any attention and loves to be as close to you as possible if you're sitting. It would be so great to have someone come give her some attention and exercise. When I walk her around the block it's about 10 or 15 minutes depending on speed. Questions welcomed! :)
