I don't plan on breeding, and my vet as well as my breeder are pressuring me to castrate my PON. What are your opinions about this topic ?

PON Digest has an article on this subject this month. There are additional issues as well. Did you sign a contract with your breeder about castrating your PON ? You need to consider ethical/legal/health issues.

I would love to attend a seminar on canine health, but none are being given in my area. Do you know of other PON owners who are interested in carpooling ?

If you live in an area with a sizable PON populations, you might consider calling around and speaking with owners about carpooling.

My PON never had allergies, but now she is itchy when pollen counts are up. Will a change in diet help her ?

Immune systems change and you might be well advised to have tests to make sure your PON has allergies and not a thyroid condition.

Are there any MDRl gene clinics ?
