seriously, you shouldn't feed a small dog one large meal a day. it should be given out in several small portions or they get fat like yours. Also, you say he runs alot, well, if you do in fact give smaller portions and exercise him alot, then take him to the vet !! he probably has thyroid problems. he will be a grumpy son of a bitch when he gets older and won't be able to walk, you'll need a small wheelbarrow.
