no correction the new code calls for two ground rods to be driven into the ground.
No,you'll need a certain size (dia) ground rod that you have to have drove into the ground .
At best, they're a waste of money. At worst, they can kill your pet. Most of those formulas contain xylitol, an artificial sweetener. When you eat it, your body doesn't release insulin. When a dog or cat ingests it, it causes the opposite. Their bodies will dump a ton of insulin into their bloodstream and their blood sugar will plummet. Without FAST emergency treatment, this will kill a dog or cat. The safest (and best thing) to do is have your dog's (or cat's) teeth professionally cleaned by your vet and then brush them daily. It costs more, but it does a much better job than the water additives and you're not poisoning your pet. Avoid these things all together. Even a tiny amount can kill an animal if they're overly sensitive to xylitol. Hope this helps.
