Because rats will keep at it for longer. These particular rats are probably bigger than some tiny dogs, but a rat is a forager, so it can be motivated to keep this up for hours. This behaviour is not so close to what a dog needs to do to eat, so it would do it to please but lose motivation eventually.
Well that's what I remember reading some years ago anyway. I guess a dog would keep going if you made a fuss of him, but you don't want to go over to the middle of the minefield to do that.

- xeonmc 2y agoBut are there more truffles in a forest than there are mines in a minefield?
- riffraff 2y agoI'm not sure, I remember going truffle hunting (a grand-uncle owned truffle dogs) and spending a whole morning not finding anything. Luckily, I never had to go mine-hunting.
- ajb 2y agoWell, that's just what I read... I'm no longer sure it is accurate. Looking at their website APOPO now actually use dogs as well. They say that rats and dogs are complementary, but they give an advantage of the dogs but not of the rats Also, I ran across this article criticising the rats effectiveness: https://nolandmines.com/APOPO%20rats.html https://nolandmines.com/APOPO%20rats.html . I have no way to assess it's accuracy.
- mystified5016 2y agoA previous article said they only work the rats for 30 minutes a day. Small mammals typically don't have a lot of endurance. Dogs and humans are kind of outliers there, as we specifically evolved for persistence hunting. It's probably just due to mass and ease of training.
