I have had pets for as long as I can remember, and always had a dog untill 4 years ago. I watch and walk my neighbors dogs whenever they go out of town and on vacation. My yard is tiny, but i live at the beach, so I consider the beach my back yard. Living off the bay is amazing, and all the dogs love the walks and calm water to chase toys or go swimming. Your fur baby will feel like he or she is on vacation, and i don't even mind giving a bath after all the fun. As for older senior dogs, I used to work in the medical field, can give meds, and have had senior pets so I know how to care for them.
