Pet Sitter Job in Humble, Texas

I am seeking a reliable person to walk my three German Shepard mix dogs, Sadie (F) Gizmo (M) and Jenny (F). Sadie and Gizmo are 7 years old and are from the same litter. Jenny is 9 years old. We've had them all since they were puppies. With my three daughters being adults now and everyone having such different schedules and trying to aqueeze in some travel now and then, I've gotten to the point where there are times I need some extra help with the dogs. I also have a one year old chiauau that I rescued since being here in Texas. When we travel he'll probababy come along but there may be times he's home as well. We also have a cat named Goober whose pretty self sufficient. We do have a yard which they can be let out into but I'd like them to be walked at least once a day. Sadie really prefers to be walked. There is no specific schedule at this time, just as needed. I will give at least a weeks notice when service is needed.
