Not all collars are created equal
Some are a recipe for tragedy.
Dogs are playing- in the scuffle, one dogs jaw gets caught in the other dogs collar- she dies. A dog left in a wire crate gets their collar stuck and dies. A dog jumps over a fence- their collar catches on the fence- the owners manage to help just in time- another is not so lucky. A dog is lying near the floor vent, their dangling dog tags slip into the grate- thankfully, the grate comes loose- but the same does not apply to patio slats.
I have sourced and added notable highlights to some harrowing stories here.
When caught by the collar, dogs tend or twist around in a circle, much like the way an improvised tourniquet is tightened. This causes rapid constriction.
Here’s what you can do:
Take your dog’s collar off whenever possible. Especially when left alone, when in a crate, or when interacting with another dog.
Get a breakaway collar. I have this one from Indi-Dog, only mine is custom entirely without D-rings. Tip: Get it in a bright colour, easier to find if it does break off.
Don’t let tags dangle. Get a pocket instead: This one works for the ridiculously oversized Berlin dog tag.
Even a regular non-breakaway collar should have a quick release buckle if possible. Regular tongue and pin buckles cannot open under tension. That can cause a delay as you need to either fetch something to cut with, or you need to rotate the dog to untwist them before you can unbuckle it.
Use a harness instead - Note that getting caught by the harness can also cause injury, but it’s less likely to cut off the dog’s air. A harness is therefore a good option when you want to let dogs play but you still need to be able to grab them easily. Still, don’t leave a harnessed dog alone.
And as always: Supervise playing dogs.
