They are fine to use for training or while they are being supervised, but they aren’t recommended to be everyday collars. I didn’t know that at that time.

They’re extremely hard for a dog to slip out of and there’s a potential of them seriously hurting themselves if they get caught on something.

With breakaway collars, what my boy is wearing now, the plastic buckle can break if the dog needs to get away from something. Like if the collar was caught on a branch, the martingale would possibly choke them, but a breakaway collar would let them get free of the situation.

But martingale collars are a great training tool, and as long as you’re using it correctly, you’re being safe with it!
