Wolfbane you can bet the farm that Riker senses when your heart isn't up to par. My brother is an epileptic that has grand mall seizures out of the blue and my moms little old mutt knows to the second before he has a seizure and jumps about trying to make him sit down. Shes saved him dozens of times when he didn't even feel one coming on. They also have Cancer detecting dogs now. These animal gifts from God should be cherished. My moms dog was a save from the shelter who was to be put down in 24 hours. So many animals that are miraculous are destroyed because there are not enough homes or people get tired of them....how sad and discusting!
