Here's the situation.
I own a bicycle shop so know a lot of people who ride bikes. Outside of city limits there's no leash law and because we cyclists spend a lot of our time on low traffic roads we get a lot of dogs chasing. For the dogs that are looking for a bite we use pepper spray. Outrunning them isn't an option for most folks as a healthy country dog can hit 30 mph.
In the past I've sold Fox Labs (the 3 oz size is very popular) but it seems like sometime in the last 2-3 years they've reduced can pressure and their stream doesn't reach as far as it used to and the stream is less stream like. We use adhesive velcro to stick the can on top of the frame right behind the handlebars for quick access.
When we're riding it's not unusual to be doing 15 - 20 mph so a strong stream that is wind resistant is extremely important. Ideally you want to tag the dog while it's 10 feet or so away as the chances of them getting into your wheel (causing a wreck) go up exponentially as they get 5 feet and closer.
I'm not worried about the hottest but it needs to be something with some kick. The reaction to a face full of Fox Labs (dig a trench with the snout) is much preferred to the junk sprays (lick lips).
Is something like the Sabre Gel worth getting or does it lose effectiveness compared to the normal liquid? I'm open to any suggestions.
