I like walking dogs so much I've done frequent free walking for neighbors. I know how to approach a dog and to read its body language. I'm retired, and available from late morning onward. Any day of the week is equally good. Dog walking is a great fit for my exercise program. I've done volunteer cat-sitting for a friend many times. I read each cat's body language and figure out what level of touch it wants. I bring in cat toy apps on a tablet. For dogs, the top priority is exercise, which is harder but still possible indoors.
