How long is the shortest prong collar you have?

Hi Cindy!

I have a friend who has a Dachsund from HELL. She's just a year old, so still a pup. Disobedient as the day is long. So, I told her owner to go get a prong collar. The thing is, I think he got one from PetSmart. I can't get it to fit right without taking out too many prongs. Then it digs into her neck. How long is the shortest one you have? I prefer the quick release kind, for obvious reasons. We did use the one he has on her for a while last night, and she did get the message. I just don't feel comfortable with it not fitting correctly. Let me know what, if anything, you can do.

Thank You!!
