I am heading out of town for a 5 nights and need someone to sit for my sweet husky George! He is 8 years old and a gentle sweetheart. He needs three 3 walks a day - morning, midday, afternoon. About 20-30min is great and ideal if at least one of the walks can be a bit longer like ~45min. He eats farmers dog twice a day. Half a bag in the morning and half at night!
