Have you taken Reggie to be checked by your veterinarian? It could be intestinal parasites or something more serious and life threatening.

Only your vet will be able to diagnose his dry heaving so please take him asap.
As far as the Purina Puppy Chow there are much better brands out there and none of them are found in the supermarket or places like Walmart. You can only purchase top quality brands at local independent pet stores.
I prefer to feed the grain free kibble brands .....check out our food forum here for lots of great information. There is also excellent information at
www.dogfoodproject.com and
www.dogaware.com and click on all the links provided at both websites.
But, first, please take Reggie to your vet as dry heaving is something to take very seriously. Good luck and please post with an update.
