Quickly! - Food similar to Blue Buffalo?

Nothing comparable that you'll find at PetsMart.  How about trying a different protein source?

Anything is fine except chicken, he is allergic.

Which leaves Lamb or Fish.  The canned foods are awesome too.  Turkey, beef, vension, salmon, lamb, and of course Chicken and the widlerness canned, but that's chicken and turkey so won't work.

I'm assuming you are serving the Blue Lamb and Rice formula, since Lex cannot have chicken---have you tried the BB Fish formula?

If you want to get away from BB altogether and must shop at Petsmart, I would go with with Avoderm Lamb and Rice ---nice food, probably considerably less kcals per cup than BB, so you will likely have to feed more.

I would probably feed By Nature Pork & Sweet Potato.

Isn't Blue Buffalo a grain-free food?  Do you have a feed store near you, you can find Taste of the Wild which has a Salmon as well as Venison protein source aside from Chicken.  My dogs are doing extremely well on that.

 Wow, I've never looked at BB's ingredients. There's five different carb sources in some of the formulas! As far as chicken sensitivity, both the non-chicken formulas list "natural chicken flavor" in their ingredients. That might not be a problem for dogs that aren't terribly sensitive but it wouldhave been enough to set off Ben, who had a true allergy.

Nature's Recipe is good - it looks like they have an "easy to digest" line with only a couple of grains and one protein source. The fat is chicken fat but that's actually better for stomach and skin problems as long as there's not a true severe chicken allergy. Fat doesn't contain enough protein to trigger most dogs.

I like Avoderm for dogs having tummy and skin issues unrelated to grain. Cord did nicely on it - they just don't have a formula with enough "oomph" to support his energy needs.

And, if you are desperate, that doggone Pro Plan Sensitive Skin really does work magic. The problem with using it is that if it works you won't be sure what triggered your dog in the first place as there are a couple of nameless ingredients like "animal fat" - is it pork? beef? chicken? turkey? and "animal digest."
 

Blue does have a nearly grain free, in Wilderness, but, that's chicken and turkey, so that wouldn't work in this case.

I personally don't like Avoderm or Taste of the Wild.

 I hope he gets over the diarrhea soon; if he's been on BB for 2 months and the diarrhea started recently, the food's probably not causing it. You may want to take a stool sample to the vet. Lex is a real cutie!!!
