Ruth:
I may have had an atypical experience with Springtime products, however, I just shipped four products (Longevity, Fresh Factors, Joint Health and Calmplex Stress Tabs) back to Springtime for a refund today. I have been trying to get six of my dogs to eat them for four weeks without any luck minus a struggle and much ingenuity on my part. I currently have a horribly neglected foster dog with me (non-GSD) and I purchased all of these supplements for him and for my other personal dogs (including my recently rescued GSD). Between the dogs spitting out the chewables and turning up their noses at the Longevity, I decided to go back to the other supplements that I had been using without any challenges.
As the packages and Springtime website directs, I did add the supplements gradually, mixed them with the kibble and some canned food with warm water and then even tried putting them in balls of canned food, hidden in the centers. No luck. I hope that this is just my experience, but I had no luck with the four supplements and I have a rescued foster dog who really needs a lot of support to get him over the years of neglect that he has suffered.
