I switched from Iams to Blue Buffalo a few months back and one of our dogs especially has softer hair but the other 2 have begun scratching so I am now looking for something else. I just read that Blue was sold to P&G.
You may be mistaking Blue Buffalo dog food with Natura, who was sold to Proctor & Gamble. Blue remains a family owned company.
Note, Blue has had recent dog food recalls due to excessive levels of vitamin D. Be sure to check you're not feeding your pups any of the affected products.
