your points are well taken and i've read articles talking about people letting dogs"chase" after black bears only to have dog come back into camp with bear in hot pursuit??
i don't know if i would NOT bring a dog, but i wouldn't let it roam free or "set" it at bear to close to camp??
it's hard to imagine that in Q/BW, or the bush that a healthy bear would be driven to go after a full size barking dog??
i guess only bear knows for sure but i'm wondering if there is perhaps another explanation??
could it be that the bears are young male's and the see the dogs barking as a challenge to there territory??
those are the kinds of bears i carry my bear spray for, there not looking for a scavenged meal, there looking for fresh meat, as in YOU!!
while they may be few and far between, that's not much comfort if your the unlucky soul that encounters one :'( :'(.
THERE not going to be deterred by throwing rocks or paddle upside there head IMO!
Like the discussion of hanging or hiding, there are a multiple of opinions on this subject!!
I wonder what the guy in canoe with dog would say now that his "deterent" turned out to be a "ATTRACTION" :( :(??
