Sitter Needed For 1 Dog In South Boston

My name is Lindsey and I have had my rescue dog Panda for a little over a month now. Panda is a lively 8-year-old Maltese mix struggling with separation anxiety, but does great at home with a friend and loves many pets. He loves taking long walks with lots of sniffing breaks. He is currently on anxiety meds and we are working through resource guarding of high prize treats. I am exploring options for when I need to travel or be gone for longer periods. I think he would do better with a sitter than a doggie daycare.
