Scary moment. Has anyone else ever had or heard of this issue?

Question

Tonight I let my dogs in the backyard to go potty and play as usual, but thank goodness I left the patio door open. We started hearing “screaming” from our boy Max and came outside to see if they our girl Nova was just playing too rough.
From the patio in the dark it looked like one had latched on to the other’s neck so we ran outside and went to separate them, only to realize Max’s tooth was caught in Nova’s collar and they were stuck.
He was screaming in pain and thrashing, which was choking Nova. In the dark I could feel wetness and couldn’t tell if it was saliva, blood, or both.
I yelled for my husband to get scissors to cut off Nova’s collar since the buckle was in Max’s mouth and unreachable, but suddenly they got loose and everyone was free.
My poor babies! Nova’s been so clingy for the last couple hours and Max has been afraid of everything. He went up to Nova at one point and started licking her next like he was apologizing for choking her.
There are a few scratches and red marks but it looks like everyone is ok. No tooth issues or serious neck injuries. And it looks like it was pretty much just saliva.
Here is the collar in case anyone is curious. Just your basic nylon collar with a loop. I’ve never heard of anyone having this issues before so I’m curious if anyone else has.
TL;DR 1 dog’s tooth got caught in the other dog’s collar. Have you ever heard of or seen this before?

Max is the tri-color and Nova is the black one.

Answer

Yes I have actually! I worked for a rescue and dogs have funny ways of attaching themselves sometimes by accident. It’s kind of like how if you walk by a cat they put their paw out and catch it with their nail.

Answer

Definitely heard of it happening. Also heard of dogs getting collars stuck on their crate and strangling themselves. So we now only put collars on for walks. They are microchipped so God forbid they get out without their collars, at least they are chipped as well. 
Collars can definitely be dangerous - especially when you have more than one. I notice my girls always go for the neck and ears when play fighting so I’m shocked they never had issues back when we kept collars on 24/7.

Answer

Glad the babies are okay ☹️❤️

Answer

There are collars that are made to break away if caught to prevent strangulation and such. I have them for our cats
 I'm glad the dogs are okay.

Answer

Poor babies!! The one who got their tooth caught, is that tooth ok?

Answer

My dog was involved in a similar accident last year. It shredded her face horrendously and the other dog suffocated as they had been left unattended for several hours by the person watching them. The owner of the other dog was shattered.

Answer

This happened to my coworker last week and her dog was terrified it bit her!

Answer

Yeah it's happened before. My brothers puppy was playing with my dog and got stuck, they were able to unlatch themselves but he took my dogs tags with him.

Answer

This happen to our dogs. Dogs were playing one dogs teeth caught on the other dogs collar. We didn't realize what was happening until it was too late. One died of strangulation. Very scary stuff.

Answer

Yup! I work with dogs and see this happen quite often. That's why breakaway collars are so important where I work because we can just unclip it quickly.
