Was hunting down in the Ellendale area and our dogs found a gut pile. His dog had a few bites off the pile and was died. We were 14 miles from the vet in ellendale and he was dead before we could get there. Less than and hour. The vet said it probably some type of varmit poison (stryknine). This is legal to use in ND. So whatever the reason the dog died (2 year old brittany), just be sure to keep them from eating dead animals while you are out hunting.
