You can find a lot of puppy collars at thrift shops for pretty cheap - would never pay full price for one. I'm getting mine at 14 weeks and was told that 8-12 inches was what was being used - then at 4- 6 months graduate to 10-14 inch collar.
What size martingale collar do you use?

My girl is 7.5 months now and she is great at not pulling on walks but I would like to use a martingale collar. While she is not fully grown would it be beneficial to buy a 12 inch collar (i think this is the correct size) or what for when she is fully grown?

You need to be careful with martingale collars that they are not too big, as the dog may be able to back out of them. I think you would need to try the collar on your dog to know if it would be appropriate. When tightened it should not be able to come off!

We bought them from www.halsbanden.com - she also sends outside the Netherlands. She will ask you to measure your B's neck. They fit perfectly!

This page has great illustrations for proper measuring. Hope it helps.
