Thanks for all the ideas guys. Smokey Joe is eating Iams
lamb & rice puppy brand (dry) now b/c it was what they fed
him at the Shelter and I'd didn't want to switch his food.Don't
really care for Iams brands, but he was used to it, so...
One vet I talked to said to switch to large breed food at
3 months. Another vet (in the same practice) didn't offer
any suggestions at all about feeding, but when asked just
said a good quality adult food would be fine.

I'm thinking I'll switch to the LB food within this next month
so he'll be completely switched over from Puppy to LB at 4
months. (16 wks) Like a lot of others here, I had not even
heard of specific formulas of chow for large breed dogs when
Buddy was a pup. He grew very big very fast but I don't
think it caused his hip problems. I believe it was genetic.
His one hip bone would pop of of the socket sometimes
when he was still under 6 months old. Surgery helped him
but could not cure the displasia.
Smokey eats like there's no tomorrow all the time, and
I don't want him to get to heavy to fast.
