after one of my dogs got court up on the dog guard with his collar in the car,and nearley hang himself which at the time driving back from the vet with him a distant of 2 1/2 mile,the only thing that safe him was the quick release beacuse the collar has twisted.
so none of mine dogs have collar on in or out,after that,no collars in cages,as well,
i would not of think with this emergency a leather collar would have break.it twist so tight that i could not get a knife or scissors under the collar,
