I have tried several different address capsules for my "low" dog. Most went pretty soon the bottom of lost, but with this product, which is a bit more expensive than the other, nothing is even after prolonged use and much wild race in the undergrowth lost. My dog has at each of its many-Puppia Soft Harness (also the best of all, also from Amazon) such a capsule, and I can recommend these capsules only continue. Are of very good quality.
