My pups love carrots, broccoli and beans!
I used to make stews for Biscuit and supplement with a LOT of veggies because it helped his anal glands so much --- it really made a difference.
Nowadays, I don't feed the stews so much, but they still get lots of veggies. Carrots and broccoli are especially liked --- and yes, apples, too.
Don't EVER give them onions, though!
Right now, they're chowing down on doggie pumpkin bread, made with plain pumpkin (and lots of it) and sweetened with only molasses.
The gas problem -- eh, some get it, some don't. Yogi always has little poots, no matter what he eats. :roll:
