Thanks Jerry, The vaccination is what I was referring to. There is no way I can keep the snakes away. I live in rattler heaven. My dogs are older so I don't wan't to do the animal trainer routine on them. I do a good sweep of the property a couple times a day. I recognize the intruder bark, but it is not allways in time. My mutt ,45 lbs., real dog , 8-9 yrs. old was in such pain that he would just stand and stare at me. With a cartoon swollen face, and piddle. Which he would never ordinarily do under any curcumstance. The other dog is 65 lbs. of fragile disposition and a pretty boy, 11 or 12 yrs. old. Palmetto and scrub oak a thousand yards in each direction. A few pines where the loggers didn't get them. I have never been beyond the hundred yard point because I can't find my snake leggins in my storage. 2.5 yrs. What is there to look at?. I am going to put a 100 yd. musket target out there. I need to learn to eat / cook /clean rabbit!
