My dog, Jilly Bean, loves her Springtime Longevity! I like to purchase in bulk (the buy 2, get 1 free) and it lasts me months! Jilly is a 3 y/o Staffordshire Bull Terrier w/ a history of skin allergies, itchy skin, and joint issues. I like to mix in a scoop of longevity with her kibble, along with a pump of Salmon oil to bind it all together. This combo has left her fur feeling like silk! She always gets compliments on how soft she is and people always want to know what it is that we feed her. Since adding Longevity in her diet, I definitely see an improvement in her skin and notice she has better mobility. There was a time when we first adopted her and she would maybe run a little too fast or try to jump up on a high surface like our bed or couch and she all of the sudden would begin to limp. Since being on longevity for some time now, I definitely see an improvement in her joint health and overall strength. I strongly feel Springtime Longevity gives her the right amount of vitamins / supplements she needs to continue to be strong and healthy. She is definitely one happy camper!
