I was looking around online and I came across a site that sells personal defense weapons.
On it they sell Mace. They sell many kinds. They sell Mace Brand tear gas. This isCS Gas and it tells you all about it.
At the end it says, CS is ineffective against Dogs. If you need a personal defense device for use against dogs, please by Mace Brand Pepper Spray. And it gives a link to the site.
Then under that item, it does say Mace Brand Pepper Spray is effective against all the dogs waiting on corners to mug you
First of all, is it true? Is tear gas ineffective against dogs? Second, if so why?
A complete WAG, but I’m guessing CS gas is not enough of a deterrent for a dog devoted to ripping your throat out to be called ‘effective’. I don’t think dogs are immune to it, but they might be partially resistant to it due to physiology.
One of CS gasses main effects is excessive tearing. Dogs are limited in their ability to create tears. Pepper spray causes inflammation; it works regardless.
Don’t laugh. When I was a letter carrier one summer I used my Post Office issued doggie mace on a dog who was waiting on a street corner to mug me. It bit through my pants leg and came within a fraction of an inch of my leg.
I sprayed a Husky once with pepper spray (10% at 2 million scoville heat units) and it didn’t do jack. Nailed the sucker in the eyes, nose, and mouth. He kept growling and being aggressive. The animal control officer got there and got the dog. Had he not gotten there right when he did I would have shot that dog. I was coughing and hacking from the blowback of the spray and it didn’t faze the husky! And no, it turned out it wasn’t rabid.
