>>2727920>Is pepper spray any good against wolves or dogs?Yes, but it doesn't stop them. Just makes their eyes tear and their noses smell, so you have a better chance of escaping.
Sprays are unreliable though, as they can always lose pressure with no warning sign. The one time I had to use them (well, thought so, at least), that can only got a range of approx 30cm instead of the advertised 3m. That was a 4 months old can that had been kept in the house most of the time - carry one on your belt in the sun, and it'll lose pressure even quicker.
If you can afford it and aren't limited by retarded UK or US laws, carrying a pepper gun (a revolver or sawed of shotgun firing what's basically a cartridge where the bullet was replaced with a pepper / wax mixture) is much better.
But really, having encountered both wolves and boars a few times now, usually from distances below 5m, I never actually needed to fight them. Unleashed, badly trained dogs are a different matter, but fighting them off usually ends up with having to intimidate or fight the owner too, so I'd want something more convincing than an irritant.
