We love Pulsar! We've seen it work wonders for dogs with allergies or that may be overweight. It's low-glycemic, single-sourced proteins, has more than the average probiotics added, and best of all, it's for all life stages! A well-made food is good for puppies to seniors. Puppies burn more calories so they just need to be fed more per pound of body weight. Try an 8.8lb bag for only $15!!!
