I personally think that the dog's intelligence is more of how it is brought up and trained by the owner, not so much of its breed, just like how we nurture kids with proper teachings.
What's most important is that you feel comfortable with the dog and that it can give you the affection and attention that you desire. =)
You can also check out the veterinary websites below for Selangor and Perak.. I find the Perak one easier to read..
Perak: http://www.jphpk.gov.my/
Selangor: http://agrolink.moa.my/jph/sel/
You can look for the quarantine sections or give them a call.
Btw - just curious, where did you hear of PetFinder from?
