Breaking news: new Purina formulations - Dr. RuthAnn Lobos on specs, ingredients, and who should consider them

Exclusive! We get the lowdown on new Purina dog foods the day they hit the shelves. Dr. RuthAnn Lobos (@petvetruthann), senior veterinarian at Purina will outline the rationale behind their new "Advantedge Plus" senior and digestive formulations, and why many of us should consider one or the other. We'll parse ingredients, specs, and the new product development process from a researcher's notion to stocking retail shelves.

We'll cover why and how dogs "choose" favorite foods, when our dog actually becomes a "senior" citizen, indications of a dog's aging, and find out what ingredients go into the new formulations and why. Dr. RuthAnn talks about why we shouldn't feed prior to a hunt, how Purina "taste tests" new foods, and defines a healthy physique for a sporting dog.

"Fix It" keeps your dog warm after a cold wet hunt, and listeners tell us what they're giving their dog for Christmas or Hannukah.
