I love to read studies about canine nutrition, but how do I know if they are valid ?

Please don't believe everything you read or view on the net. Check out the reputation and sources of all studies. Some are flawed.

A well known "expert" in PONS advised me to use Colloidal Silver on my PONS. What have your heard about it ? 

 Consult your family vet for all health conditions. Please read this month's article on the subject of Colloidal Silver and check the links at the bottom of the article.

There is a beautiful looking Rescue which looks like a PON, but I am unsure if it is genetically a PON. How can I tell if there is no paperwork ?

New genetic tests have come onto the market which will determine if this Rescue is a PON. Please consult this month's issue of PON Digest for more information.

Why are most PON rescues, males ? Are male PONS more difficult to deal with ?

Not at all ! Perhaps some owners lack good training skills, hate grooming or have fallen onto bad times. There is no significant difference between male and female PON temperaments.
