A lot of pet owners have a schedule for their pets which I follow diligently. Food, treats and medicine are given at the time specified by the owners. I always ask permission first before giving pets anything that is not currently apart of their regimen. Potty breaks when needed, lots of pets and play (thats the best part, right?) and in the past I've even sent text/picture updates to some owners who I've become friends with that were particularly worried about their pet. As for my own pets, our cats are young and play with each other so I spend a bit more time with our dog Leo taking walks and playing tug-o-war since he's the only dog in our home (so far). When walking a dog, whether its my own or someone else's I always pay special attention to when any other dog gets close for both parties safety. I also keep water in a cooler in the truck so the dog has clean water to drink.
