Weaning off the puppy food

I am trying to wean Bacon off Puppy food. He is 9.5 months old right now. I attempted to change over from "Taste of the Wild Puppy Formula" to the adult version. I slowly introduced the adult over a two week period, but he didn't take nicely to it. He had extreme gas and soft runny stools.

I went back to the puppy formula and he's back to normal. My question is how long can he go on the puppy food? Also, should I attempt to move to a different brand's regular formula? Not sure if you all have Taste of the Wild overseas, but it is a pretty good quality grain free food...

Most companies will say up to a year for the puppy food. When you say you introduced the new fod gradually were you mixing the two together? Start with 90% of the old and 10% of the new and reduce the old by 5-10% every day or two. He may still have gas or runny stools but his system should adjust and adapt until the new food is normal.

Thanks Jstaff. I started with a 70/30 ratio. I started the 10% mix in and will go slow to see how he reacts.

I would have thought 9.5 months was too early to change to adult food? Zeus is 11 months old and still on puppy food...

My pup was put onto adult kibble at 8 weeks and then I decided to feed raw! She's been raw fed since about 10 weeks or so.

I'd say you don't need to bother with puppy kibble!
