One of my dogs was diagnosed with a heart murmer a few months ago. He recommended this product, and so far, she seems terrific.

Pros: Good for the heart and overall health of the dog

Cons: none

This is a preventative for the circulatory system. It should be taken daily for a long time period not just now and then or when you think you dog needs one.
I take one, too, now while I am younger to help prevent problems when I get older -- do the same for my dogs. As with anything that must be taken daily for long periods of time, it will start adding up cost-wise, but worth it compared to vet bills later in your dog's life.

Pros: A preventative to help the circulatory system

Cons: cost

I use this for my pets daily. It helps with neurological and cardiovascular systems. It is shown to increase pets lives by 10%. I am a firm believer in holistic care. I take the human form myself.

Pros: Co Q 10 is shown to increase life expectancy

Cons: none

Why wouldn't COQ10 be good for your pet since it's so beneficial for humans! I wouldn't hesitate to supplement my dog's diet if he needed it. I love to hear about owners taking such good care of their animals.

Pros: beneficial

Cons: another expense!
