Dogs against rodents

That's actually dangerous. Rats may carry diseases and if your dog was ever bitten, chances are she would've gotten sick as well. My aunt is very particular about not giving the dogs a chance to wander into the kitchen where they can get into dark corners where rats may be hiding. Her toy poodle loves looking for rats even when they were still in Manila. I would not let dogs of mine near rodents as well because it may be fatal to them.
