I have two pointer mixes (60-70 lbs. each, I'm sure a smaller dog may not have been so lucky!) who have been "exposed" or bit the "bufo" toad. There was immediate foaming and I was able to make him drink alot of water. This has happened twice. I've since noticed as the summer is progressing the frogs getting trapped in the dogs outside water bowl. I deduced that by putting a container of water away from the area where the dogs go, the toads are trapped and moved away.
