This collar has no buckle! That is a glaring safety issue if the collar were to get caught on something and couldn't get released. This collar can only be slipped over the dog's head and then tightened to fit. To remove it has to be resized large enough to slip back off head. It's as if the thought was to put the collar on the dog and leave it on. That however is not how martingale collars are meant to be used. They are training collars, not everyday collars and the constant adjusting and readjusting to put on and remove are a pain. The chain is also made of large links which don't slide smoothly. My bad for not noticing there wasn't a buckle when I ordered it, but the design is flawed.
Ordered a collar and leash. They seem to be well made but they are slightly different colors which is disappointing. It would be so much nicer if they matched.
Fit our 150lb Newfoundland perfectly with plenty of room. Great quality even has a tab for her ID tag
