Not a direct answer, but I think it might help address this question.  We trapped gerbils in coastal sand dunes, and in some of our plots, we had foxes who learnt to look for the Sherman traps with a gerbil in them, take them away, and try to break them to eat the gerbil. As a solution, I tried a method that a colleague told me worked for him in the Mojave Desert - we collected human urine in a bottle and added a few drops on each trap roof. The next morning, the entire plot area was littered with fox tracks, indicating that they had moved between all traps, deposited their urine and feces on some of them, and likely sniffed all the others.  The result was that no gerbil entered any of the traps, and there were hardly any gerbil tracks in the plot during that night.   Moral of the story - a canine moving freely in your trapping plots may reduce your trapping success.

We have been placing trap cameras along our saliva collector in a forested area in our campus, where for the past 4 months some semi-feral dogs have established their campsite (and had a litter). We see the dogs roaming around our collectors, and once they do that, no other species come to that particular collector. Also those non-dogs that come are visibly more attentive to their environment and run away a minute before some dogs shows up.

So I'd say that your dog is not helping your research. He might be more useful at the lab. :-)
