My pair of dogs get ear infections pretty darn often. I'm almost certain it's something in the house, as I've switched foods multiple times and the best one we've found cleared up everything but their icky ears. While I'm trying to figure out and put a stop to the source of this, I've been giving them rooster booster in just about every other bowl of water I set out. It's seeming to make a little difference though it might be my imagination. Could the rooster booster be helping? Will it hurt them? Can it hurt my cats who drink from the same bowl?
