We ordered about 40 of these for our Alpine Dairy herd in Southern Indiana and put them on the goats at the beginning of breeding season. Even with all of the 'rough-housing' that goes on at that time, the collars have performed wonderfully!
There have been no chewed-through collars, no broken buckles, and only a few 'slipoffs'. (For safety, we order them large enough that if the collar gets stuck on something like a fence, it is possible for the goat to pull the head out of the collar. Under normal circumstances the collar is heavy enough to hang low on the neck with the head up, and stays on as it gets caught on the erect ears when the head is down.)
Visitors to our farm love to see the names on the collars, and it helps confirm the identity of those goats that look almost identical.
We'll be ordering more for the new crop of kids in the Spring!
