Riley is on a diet!

I have the most wonderful little dog.  He is a papillon and I got him from Small Breed Rescue.  But in the 4 months that I've had him, I've managed to cause him to gain 3 pounds!  He loves to eat and I love to feed him!  But I do not want him to have problems from being overweight so I'm going to be diligent about limiting his food.  We are both on a diet!
