Going to Canada for Christmas need dog sat for approximately 48 hours

My dog is a 1 yr old Affinpinscher mix. He is highly anxious and has separation anxiety. Unfortunately, my relative in Canada will NOT allow me to bring him - hence the quick trip. He is very sweet and loves people, not so much other dogs - he is fearful. He has no agression issues. He simply needs to be walked every 3-4 hours or if kenneled can stay in there up to 7 hours. Once a day feeding. Very energetic. Loves to play fetch with his toys.
