Sort of. Or, just a bit like the HALT product you can buy and which US Postal Carriers carry for use against unleashed, aggressive dogs. There are at least three differences, however:
1. It is generally quite a bit more potent, having a larger percentage of the active ingredient.
2. It has a much greater range (perhaps 8+ meters) while still maintaining an effective dispersal pattern.
3. A can of bear spray is larger, providing a continuous (not that you would necessarily use it in one continuous spray) 8-9+ seconds of spray.
