Review on 🐶 Durable Martingale Training Collar for Dogs and Puppies - Big and Wide, Small to Extra Large Sizes (Medium, Floral Design) by Tiffany Young

We got this for our 10 week old Doberman puppy. I didn't want an expensive collar as she is growing so fast. I measured her neck to make sure the collar would fit. But when we got it, it was too big for her. Having no other choice, I used it until I got a replacement. The second day we used this collar, our pup slipped it over his jaw. Fortunately, I was in the middle of her training and noticed it immediately. My husband and I had to get it out of our mouths. It could easily break her jaw. I do not recommend this collar! We have several other martingales for our older dogs but this is a poor design.
