I recently bought a Martingale collar and was wondering if any of you guys have used one or have any tips. They were originally designed for greyhounds because they have heads that are smaller than their necks and can slip out of a regular collar easily. We've had the same problem with Archie because he has a little terrier head on a big Corgi neck/upper shoulder area. So, when he needed a new collar (growing up so fast, *tear*) I decided to go with one of these. The problem is that I'm not sure how loose to leave it when he wears it regularly, thoughts?
Here's a link to the kind of collar I'm talking about.
His is padded on the side next to his neck and nylon webbing (in a festive Celtic pattern) on the outside. It also works with the material and not a chain.
