Early summer is when I take a good look at my dog's weight and build. This is a time of dimished activity, at least for a house dog like mine, and, consequently, an opportune time to put the dog on a diet in preparation for hunting season just a few months off. Mine weighed in at 41 last vet visit and struck my eye as a bit chunky. I reduced the height of her food in the coffee cup I measure it in by about a half inch. It's not enough of a reduction to make the dog uncomfortable and its just right to knock off a couple of pounds before the fun begins. She's looking trimmer.
