Bufo toad, yuck!
My young dog Kelly found one in the small run I have for them. Thank Heaven he didn't touch it. I put them back in the house and went back out with a shovel. Hit him once, didn't faise him, took the shovel and tried to cut him in half. No luck but he wasn't moving so shoveled him up and threw him in the road where a car did him in. I put him over the fence so no other dog would lick or roll on him.
He was the first I have seen in my yard.
