Hi!!
We feed our guys Royal Canin Venison and Potato. They can graze on it whenever they feel hungry. I buy the small bag as it has small kibble.
Because our Chase had colitis and has to be on a special diet is why they all eat this. They also get a Tbl. of canned Prescription diet i/d for Oz and Jack and Prescription diet z/d for Chase.
All tummys are good and poo schedule is good also

.
Since Jack has been eating the Royal Canin and i/d he has not had trouble with his anal glands.
Ozzy is a licker and will lick the other dogs and his fur, like a cat. He gets a little strip of "Lax'aire" a lubricant in case he has a hair ball.
Yes these babies can have very sensitive tummys.
