They don't. Not against proper pastor dog that are usually (much) larger than wolves and extremely territorial.

The spiked collars is used because dogs are in inferior numbers against even a small pack of wolves... but on the other hand any predator is easily dissuades to search for an easier prey when faced with even minor resistance.

To answer the headline... Oil smokes and burns when it's hot - why aren't our cars always billowing smoke?

(Because your brain isn't a sponge in a bowl of soup).

Alcohol is an antiseptic, not an antibiotic. Alcohol also does not kill all bacteria or fungi. Did you know certain bacteria actually can create an endospore in response to harsh environments like alcohol allowing them to survive sometimes up to 150 degrees Celsius and other seemingly unsurvivable environmental conditions.

Have you never used hand sanitizer and wondered why it says “kills 99.7%” of all germs?

I have always thought that if modern technology were used to make something nutritious out of various weeds, we'd all be better off. Giant thistles. Ragweed. Dandelions (yes, I know the French and others eat the greens, but they eat snails, too). Burdock. If there is a more useless plant in the world than burdock, I'd like to hear it. All that vegetable energy used to produce a burr that winds itself into any kind of fur so tightly that it's easier to cut or burn it out than to try to extract it. Take that perversion and use it to make a nutritious seed! Cockleburs, all the other "I'm going to lodge in your hair/fur and go for a ride" plants. Pigweed. I mean, pick one. All you guys going for a PhD in biology, find a weed and find a way to make it a food crop. You don't even have to change the plant, just find a way to process it into something edible or useful. PLEASE!
