Review on Bluebird Martingale Pet Collar - Nylon Guardian Gear by Shannon Smith

We have just had a puppy (12 weeks old) he is a Beagle Spaniel mix and weighs around 9-10lbs. His neck is around 10-12 feet long and fits perfectly at the smallest size. I thought the puppy would flinch and run from the collar but he's a great boy. Anyway, while the martingale collar is awesome, he couldn't take it off even if he tried, it's like a chinese finger trap, if he tries to pull it back it will tighten and he won't be able to pull it back , if it is So. Great but for any dog so they can't break out of the collar and walk without an ID or just can't walk at all! Great purchase for a puppy and any dog!
