Years back visiting a guy's cabin with my springer spaniel got me a hundred dollar stomach pumping bill because the dog found the mice poison. It happened again a couple weeks back when the wife's son's pup ate a d-Con bait out in the garage. It probably happens enough so that dog owners should be more prepared to deal with it right away. We called a vet immediately and he said to give the dog hydrogen peroxide a few of times to induce vomiting until all the green d-Con color was gone. Hunting dogs get poked with sticks and get stuff in their eyes, so carrying along some antiseptic and eye wash water might be a prudent thing to bring along.
