Definitely a big difference!

Hopefully that dog gym can order it for you...our local food store is great about special ordering things as well. Love it when stores go out of their way for their customers...makes going back very easy!
When you feed the wings, just hold them...that should make it easier for you.

We've been feeding raw for a couple years & I have to hold boney chicken for a couple of my dogs as they're gulpers. But until you know your dogs eating style...hold it for them to be on the safe side. Definitely a good idea for that peace of mind.
Good luck & I hope you're able to give the frozen patties a go! I think I read someone say here that the frozen patties are half the price. Not sure how true that is as I've never even bothered to feed the freeze dried but it will make your pocket book a bit happier if you can get them! We actually get the large patties (cheaper still & where I have so many it's just as well). So a 6lb bag lasts us 4-5 days...but that's with 7 mouths to feed!
