Bought for my new puppy and fits snuggly but wouldn't be able to make it any smaller. Feels soft enough to be gentle on her neck but sturdy enough that I have no safety worries.
I like this collar, it's well made and strong. The purple colour stands out against my dogs reddish brown coat and she likes that she doesn't have to wear it around the house and that it's easy to clip on when it's time to go out.
