Teddy looks good to me in the picture
, but as KJC indicated, it is hard to tell with pictures. As long as his bones are protruding when he is standing up, I think he is in good shape.
I had to hand feed Max his first year. We played games with food. He performed tricks and I would hand him kibble out of his bowl. I got him to eat more on his own by playing "Kibble in the Kong," putting a whole bunch of his kibble in his Kong. He is a big chewer, so I used the small black Extreme Kong. You may try something like that.
