Well there you go, G-3 has done it for a long time so it should work well. Stay with the cheap dog food though, like we are gonna spend $30 for 40# when we can get 40# for $10. lol. The more expensive stuff has a lot more meat products in them. My wife's Bull terrier eats that $38/40# bag stuff so boy do I know.
As for prices, you have to search around. For customer support, organic farms has been the best so far. I have not gotten a reply from 6-10 others in 3 weeks.
And feeding them dog food should make them really good for catfish fishing!!!
I love taking my kids fishing, now if I could just manage to fish at the same time.
