I have many stops where the dogs love to jump in the truck to get a treat. This took years and a lot of patience (as well as cookies) to achieve. Other stops have dogs where I will not get out of the truck if they are out. I do not trust any dog especially when it is in protect mode.
The dynamic between dog and driver is completely and fundamentally altered once the dog jumps up into the truck.
Outside of the truck is the
dogs territory. Inside of the truck is
your territory and I have seen some of the most protective and ill-tempered dogs undergo a complete personality change once they jump up into the truck and get a biscuit.
I have been growled at and snarled at and threatened plenty of times in my 26+years of driving, but
never once in that time has a dog behaved aggressively towards me
after it had jumped up into my truck.
I make it a point whenever possible to take a minute or two to try and "get to know" a new dog with its owner present. First impressions are everything as far as dogs are concerned and the minute or so of time spent will pay for itself in the months and years to come due to the dog being friendly instead of aggressive.
I get a lot of flak from people who think I am wrong for handing out biscuits but the fact of the matter is that I have a
system for dealing with the dogs I encounter that keeps me safe, it keeps the dog safe and it keeps the dogs owners happy and protected from liability. Criticize my methods all you want but my
100% success rate at avoiding dog bites in 26 years...as well as the fact that no relief driver has
ever been bitten by one of "my" dogs... speaks for itself.
