I was told to feed my furbaby Pro Plan for puppies and then the guy at the pet store said that it was CRAP and that nutrience would be better for the puppy

. I bought 2 big bags of Pro Plan and a couple cans of soft Nutrience food and decided just the other day to mix the two of them but Mylo ended up with some pretty nasty gas....It was really, really bad! So bad that my husband left the room LOL. Now he refuses to just eat the hard food. He doesn't eat as much as he did before I introduced the soft food. I was a little worried because I didn't think he was eating enough so I added some more nutrience with the pro plan and he ate like he was starving to death. Can I mix the two and just hope the gas goes away before my husband does
Or can someone recommend a good dog food.
Thanks
Jen
