Mine love the green veggies and have never had any significant gad from them that I noticed. Maybe just because it is new to his system? Mine eat frozen green beans by the handful. Broccoli is gassy but peas, green beans and carrots shouldnt be so bad. Yes carrots DO come out the other end. haha Cutty doesnt chew so well so his are almost whole even. lol Same with kids tho really. My 1 yr old started eating raw carrots and it comes out in the same chewed pieces she ingests. Cooked carrots seem to absorb more into her system so I wonder if it would be the same for pups? Really it is used as an empty no calorie snack to keep my babies trim.
