I noticed the other day that when I'm feeding Spike veggies (acorn squash in this case) he takes everything I hand to him, chews it up a little bit and appears to swallow it. After a while, I noticed his beard looking swollen. I pressed on it and realized that all the pieces he was eating were sitting in there! I stopped feeding him because it made me nervous and after a little while he swallowed all of those pieces. I have just never noticed this before and am wondering if it's a normal phenomenon. Anyone know?
