There are a few that have been reported, but 9 is the number I found with a quick google search.
9 known Labrador Retrievers in the Philippines
-Three in Baguio
-One in Laguna
-Two in Quezon City
-Two in Bulacan (just outside of Greater Manila) -- both of these dogs were identified by vets and owners as purebred Labradors. One was an abandoned dog found wandering on a farm; he had no collar or tags. The other, also without tags or identification, was owned by someone who summered their property and left him there all year round to guard it. They said they called him "Kit" and they liked his company...
