My boss thinks my Lab Mix is fat. When we got him a little over a year ago he was 82lbs and looked thin. He's now 107lbs and seems maybe a bit heavy from us not exercising much in the winter, but he's not fat enough for me to worry. You can still see his ribs if you look for them. What do you guys think? I should get DH to hold him for a good side picture. The vet noticed his weight gain and just said we should get a little more exercise - which is true, we used to walk 3mi/day but not when it's cold and we've had a lot of cold and snowy weather this winter. but really.....you can tell me if you think he's fat.
