Angel, like I've read about a few dogs, has her weight go up and down. Never a drastic weight loss, but just enough to notice, then after a while slowly goes back up. This happens every few months. She eats plenty.. This normally happens when the season is changing, could that possibly have anything to do with it? She is still super active and playful so she doesn't get lethargic or anything. She sees the vet a couple times a year for a checkup. Am I just over reacting and getting too worried about the occasional drop in weight??
