Yes, it does.

Moreover, there is such a thing as “third-hand smoke” when it comes to pets. “You know the smell that lingers in smoking areas, and on clothes and hair after a party or a night out? This is “third-hand smoke”, a cocktail of toxic residue including arsenic, cyanide and lead that gradually coats every surface. Second-hand smoke eventually dissipates from a room, but the third-hand threat remains.
Not only does it linger, it grows with each invisible coat. And on every surface it touches, it combines with the chemicals in the carpet, the chemicals in the upholstery, the chemicals in the laminate flooring, in the silk flowers in the vase, every iPad and cell phone, and on the surface of every pet bed and toy. It even builds up on our pets.
We can wash our hair and launder the clothes, even steam the carpet, but how often do we thoroughly bathe our pets? The residue builds up on them as well. When they groom, lick their paws, chew their toys and nuzzle their noses down into those plush beds we provided, they are in direct contact with the cocktail of every environmental chemical, cleanser and airborne toxin.”

We changed from proplan to blue because we heard good things and we wanted to feed our 3 dogs better but now maybe not such a good idea.
i have to be honest…i used to feed blue wilderness. i LOVED that food…until they changed the formulation. it caused serious problems for my IBD-sufferer cat, so i stopped feeding it. it caused him uncontrollable diarrhea. my other cat also starting having bouts of diarrhea after the change, so i switched to Wellness.
maybe try Wellness CORE? we have had quite a bit of success with it.
Laura- that’s what one of my friends said too that they changed the ingredients. My husky could not stomach the blue so now we’re dealing with diarrhea bland diet and reintroduce what we use to feed them.
i’d say it’s been about 3 years? basically, when they started advertising heavily on TV and in the papers, it was immediately after they were purchased by another company. that’s when they changed the recipe…and it’s a shame, because it used to be a great food.
other options i’d consider: Horizon Pulsar, Costco’s Kirkland grain-free, Merrick (this didn’t work well for my dog but it does for many others, and it’s very affordable), Acana and Orijen (though these may be too rich…tread lightly here). if you hit Pet Valu up in Perry Hall, they should have free sample bags of some things to try.
