Firstly, you need to realize that not all dog food is created equally.  Many lower quality dog food contains low quality grains, fillers and preservatives.  Also, they often use meat from dead and/or diseased animals that is not safe for human consumption.

Will this kill your dog?  In the short term it usually won't, but it can lead health problems for your dog further down the road.

Simply put, most dog foods lack enough of the nutrients that are essential to your dogs long term well being.  Yes, they contain enough for your dog to survive, but by no means enough to increase their vitality, lifespan, and fight off disease.Just like humans,dogs can benefit from supplementsfor many of the very same reasons we do.Dogs need a well rounded diet combined with the right amount of vitamins, minerals, antioxidants and essential fatty acids in order to prevent illness, disease, and promote longevity.

Deficiencies in these essential nutrients often shows up in poor health, illness and/or behavioral problems, disease, and even premature death.Many dog owners, in general, only supplement their dogs when an illness (caused by a  vitamin or mineral deficiency) arises.Though this is better than not supplementing at all, bit bear in mind that you may not see any immediate results if you leave it  until an illness occurs ( even the manufacturers claim otherwise.It requires time for the supplements to take effect and some owners do not have the patience to see it through.

My advice to any dog owners is to consider a dog supplement for their dogs before an illness strikes.
Prevention is always  better than cure.

Not only will this save you money and headaches in the long run, but your dog will enjoy many more healthy and happy days.
