Whether online or in the local pet store, there is a bewildering variety of pet healthcare products and services to choose from. Diets and supplements, ancient herbs and folk remedies, and even high-tech treatments like hyperbaric oxygen tanks and laser therapy. Everything promises to give your pet better health and a longer life, and isn't that what every pet owner wants?
