What Makes Them So Good?
Safety First
At Aspen Pet Products, the safety of your pet comes first. Because of this, our Pup-RRR-Mint Sticks are made in layers that seperate and naturally fall into smaller pieces as your pet bites into them. Additionally, Pup-RRR-Mint Sticks don't have large pieces at either end that can get swallowed and potentially cause intestinal blockage.
We have gone to great lengths to keep your pup safe but, as always, keep an eye on your pets any time they are enjoying a treat to make sure that they are swallowing and digesting properly.
