I'd say skip it. Sounds to me like he's trying to tell you he's not hungry, especially since this happens on a regular basis. Maybe reduce the amount you feed him a bit. Most of the time the amounts listed on the bags are too much, especially if you are giving treats too. The stuff I feed says my 130 pound malamute should eat about 10 cups of food a day--he eats four!

One of my siberians only eats every second day. He's been like that since was a puppy. His weight is perfect, he has tons of energy, his coat is in great shape. I figure he's just better at managing his intake than I am--Muskwa never eats just because it's dinnertime and he thinks he should. He waits until he's hungry--I should learn from him, I probably wouldn't be trying to lose 10 pounds if I ate like Muskwa!
