I thought Jackson was getting a bit pudgier for him lately. He wasn't fat by any means, but a bit 'pudgy' for my liking. He WAS getting 2/3 cup a day (but he's also chewing bully sticks a lot, stuffed Kongs, training treats, some canned food, etc, due to being inside a lot and being bored) and we honestly just haven't been doing as much exercise stuff as usual. It's been so cold for me, and I just got lazy. So I cut him back to 1/2 cup per day and I've noticed a small difference in the last week. It's something nobody else probably would notice but I do. And he's not acting starving or anything.
Maybe cut back on the canned food? 1/4 cup kibble does seem like so little. Mia is what, like, 6-ish lbs? I don't know if I'd wanna reduce kibble (if that's her 'main' meal) anymore.
