We watched samspon in the back yard, and saw what we thought was a harmless frog hopping around in his kennel, we didn't think anything of it at the time, within 10 mins after we brought him inside for the night, he started shaking in his crate, having seizures and convulsions, and pawing at the door to get out, so we rushed to see what was the matter..we let him out, and he was foaming from the mouth..we immediately let him outside for air..cooled him down with a garden hose, because he seemed very warm, and called the vet and he asked us if he had been exposed to anything and we remembered the frog..well it turns out it was a toad that he'd probably eaten, and our vet told us that they are posionus to dogs, and to spray the hose at his gums and down his throat, which we did, but it was too late..the posion got to him, all within 15 minutes and he died...it was a horrible thing to watch and experience. We know Delilah misses him, she's never been the same.
