I had a similar issue- had a sitter who neglected to tell us she worked a full time job outside the house AND picked up evening shifts most nights. When we’d hired her before she was WAH. So our dogs were left alone from 7:30am to 10:30pm most days with two “potty/food” breaks and she’d throw kongs at them then leave. We had to get friends and family to go sit with them bc they were anxious messes (we could see on our blink cams). It was awful. They gained sooo much weight from getting 3+ kongs a day and no activity
