Here's the latest, greatest Science Diet ad. Science Diet has been reducing their pricing in order to make themselves more affordable by the consumer. We're glad to be able to offer these lower prices. This ad features large breed dog food that's been tested to help the joints and other problem areas on large breed dogs. The St Bernard in the ad is our Sabocca. He's coming up on seven years ago. He had to have some surgery done a year ago. He tore a ligament in his knee. The veterinarian told me that all of the blood levels on him were perfect. The small puppy in the show is our Felina. She's now a mother herself. We made sure to let our friends and family that adopted her puppies were to use Science Diet puppy food. The food is tested to boost both brain development and agility.
