Sitter Needed For 1 Dog In Riva

I'm looking for a great sitter for loving senior golden doodle (100 lbs), who stays on first floor (he can no longer do steps). You should be able to walk him regularly, approx. 2-4 20 minute walks a day depending on what he needs. If weather is good he loves to just sit outside (but will need you to stay with him-no fence). He may need help getting his back leg footing if he slips or can't get his footing once he has gone to the bathroom. I also need someone who can provide overnight care, basically just someone to stay overnight and give him some attention. Will also need to feed him and provide one pill with breakfast. Non-smoker. Home is comfortable 3 story TH. As my dog cannot go up steps you would need to bring food/water/treats down to him. The first floor is comfortably furnished, wifi, TV, powder room and outside access.
