Dali ra kaayo ang pagpamember. You can download the membership form at
http://www.pcci.org.ph/downloads/membership-card.pdf and two (2) ID photos. (according to mypetstation - they have original membership card for free). When you mail the printed version with your ID photos, PCCI will mail back to you the original form, which you will mail back again for them to process. So if you can already get the original form, so much the better.
With your membership form, you can also already mail with it the PCCI of your GSD. Make sure you sign Section B at the back. Make sure also that you keep a photocopy just in case you lose the package in transit so you can still give PCCI the name and number of the card.
Enclose a check payable to "Philippine Canine Club, Inc." or you can also choose to give cash (which I don't recommend as you might lose it (cash is hot).
The registration fee is P660, transfer fee is P308 + courier charge (one way) P 115. so if you choose the printed form, you will have give 230 for roundtrip courier charge.
I suggest you give them a call after 3 days to ask if they received your package. They can give you feedback immediately. After that, relax and wait for it to arrive in two weeks.
