Not too much at all. I agree with FrogFace on this. However, I want to emphasise, he is a good weight as long as this is maintained. Are you using daily feedings? If so, he is not as fat as he should be. If you have adopted a more natural(not overfeeding daily) feeding schedule, he looks as he should.He looks pretty good. I like to keep mine a little bit rounder, though, for a buffer.
