Pet Care Needed - Full-time / Part-time

Looking for a sitter for 1 dog. Must love animals and be highly experienced with large dogs. My dog is dog reactive but through training has come a long way - as long as you cross the street from another dog he won't react. He's also a senior so has slowed down a lot. Need someone ideally to stay overnight with him, but open to someone coming by multiple times a day to feed, medicate (his pills just go in his food and he eats them readily), walk him, and give cuddles. Non-smoker.
