We went through 4 kinds of kibble with my dog and finally found the one he likes (it is grain-free kibble, with 70% meat and 30% veggies and herbs). Through the first change, because I lacked some information, we had some problems with his stool and gas (I feel bad about it; we went back to the previous kibble for a while then). Afterwards, we tried to transition more gradually to help him get used to the new food.

I was wondering, if I want to change flavor of the kibble within the same brand and the same line of dog food, should I do it gradually as recommended by many vets for changing dog food? I don't want to cause him any more distress, but is it different enough to cause him gastrointestinal problems?

If it were my dog, just to be safe I'd do it gradually across four to seven days, especially since I know the dog has a history of gastrointestinal problems. During the nine and a half years I had my dog, I changed food several times and developed an easy system. I used seven empty peanut butter jars, labeled them Day 1, Day 2, through to Day 7.

In the jar for Day 1, I'd put mostly old food and a bit of new food. In Day 2, I'd increase it slightly. By the middle jar, Day 4, it would be half-and-half. Day 7 was the reverse of Day 1. I'd do this before the old bag was empty, then leave these jars sitting in a row in order. That way, when the old bag was empty everything was set to transition into the new bag. No worries that I didn't leave enough for a proper transition.

Often, I'd have a bit of kibble left over at the end of the old bag. I'd get another jar and fit it into the row of jars where it fit best. I remember one time half a day's ration was left so I fit it into the middle and filled it from the new bag. I then labeled it Day 3.1 or something weird that I knew meant it should go between Day 3 and Day 4. It doesn't hurt the dog to transition one day longer.

Transitioning might not be necessary, given the parameters you mention but like I said, if it were my dog I'd do it to be safe. On the other hand, if you see your vet in the meantime you could ask them for advice.

    Thanks, and great idea with jars :-) I think I will talk to my vet as well, since I planned to visit him soon, and I will comment what they told me, but transitioning seems reasonable. Mar 10, 2020 at 14:40
