Since switching Jake to grain free (instinct)I have noticed he seems to want to eat only about 2-3 cups a day(I supplement with leftovers -liver-cottage cheese in small amounts and ground veggies)about another cup per day.He appears to have lost some weight but mostly in gut area (great hourglass shape)and his volume of poo is cut at LEAST in half.Is decreased appetite and poop volume normal when grain is cut out?All seems OK but he seems to drink a little more.Energy high coat good no itching.
