Quiet,
My first suggestion would be to immediately stop feeding crappy commercial dog food that you buy at the grocery store. Find yourself a pet supply store that sells holistic/natural human grade dog food. You will notice an improvement in your dogs within days. You may notice a cleansing effect(soft stool) at first, but the benefits of feeding quality food will be very apparent within the first week.

As far as excessive under coat, it could be genetics, could be general health, could be parasites, could be a number of things. I would first start with diet, have a fecal sample checked for parasites, and get a good de-shedding brush (I like the "Furmanator". It works great).

Age is another factor. How old is your dog? As dogs(and horses) age, there are health issues that can inhibit a dog from being able to shed. Thyroid function and Cushings come to mind.

Let us know how it goes. This is just an opinion and some dogs do just fine on it, but Pedigree is crap and you are doing more harm than good, feeding your dogs this food. Again, JMO
