As with any human or table food, don't feed your dog too much, but dogs seem to loooove popcorn. We find that about a ratio of 10 for me, 1 for you works out pretty well! Mine especially love to catch it in the air. Of course, their skills vary.
Chief has excellent eye to mouth coordination. If you lob it up, he catches it nearly every time. Actually his timing is amazing. He opens his mouth at the exact second to catch the kernel. Kind of like a frog.
Bella, on the other hand, is not so talented ... unless she means to hit every piece with her nose. Yep, she goes to bite it out of mid-air yet it always hits her nose. Then she has to scramble quick to get it before Chief does. She also does better with a line drive than a lob. Then she tends to bat about 250. Not bad, but not all-star material either.
