I purchased these collars for PAWS New England rescue because I know how important the correct collar is for a rescue dog. We have 2 dogs from PAWS and they always wear Martingales. I was also impressed by the personal note of thanks I received from Bernie at Canis Gear. That note shows that Canis Gear is dedicated to excellent customer service. If my rescues ever need new collars, I will certainly log on to CanisGear.com.
We've used Canis Gear collars at our shelter for a long time, because we know they are high-quality at a budget price. But we've only bought the collars with the plastic fasteners. I decided to buy some with the metal fasteners. The metal is highly polished and very smooth. The fastener is also a little easier to unlatch, than the plastic. I think it might be more secure and durable than plastic. Pleasantly surprised!
