If you want your dog to live it's happiest and healthiest life, this is very important.

Do you know what it really means when dog's won't stop licking their paws?

Or the horrible reason why dogs chew grass?

Or the one meat dogs should never eat?

According to Dr. Marty Goldstein — one of America's top veterinarians — these are examples of innocent mistakes almost all dog owners make when caring for their dog.

Research suggests that it's putting many dogs at risk of serious health issues. And news of this has caught the attention of the media.

"It's an epidemic. Over half of all dogs over 10 years old will get cancer," says Dr. Goldstein. "That number has doubled since I graduated veterinary school 40 years ago. But if you know the warning signs, you may hopefully catch it."

According to Goldstein — who has appeared on shows such as Oprah, Martha Stewart, and has over 40 years of experience with dogs of every shape and size — certain dog foods contain a dangerous chemical that can wreak havoc on our dogs' bodies.

This, in turn, leads to joint problems, smelly breath and poop, weight gain, itching, allergies, and even early death.

Fortunately, by learning the warning signs of danger, Dr. Goldstein has seen thousands of dogs improve their health. Dr. Goldstein actually discovered this trick — which anybody can do, right in their home — while working with his own Golden Retriever, Daniel. Daniel lived to be 19 ½ years old… over twice as long as most golden retrievers.

"It's easy, and you don't need to change your dog's food. It only takes about two minutes a day," Dr. Goldstein said on a call with reporters and industry experts.

Now, for the first time ever, Dr. Goldstein has created a short video where he explains everything about the true cause of canine health issues, including how people can naturally help their dogs stay healthy, on their own, right from home.

The video is presented below by Dr. Goldstein, free and uninterrupted.

So far, the reviews have been stunning, with some viewers saying their dogs' health improved in a matter of weeks or even days.

One viewer commented: "This is amazing! If you want your dog to live a long time, smell better, and be happy, these tips are a godsend. So easy and so important."
