Street dogs, commonly soi dogs (in Thai soi means 'side-street', 'lane', or 'alley') in Thailand, are ownerless, free-ranging dogs. These dogs are sometimes rounded up and sold as meat in Vietnam and China. It is estimated that there are about 8.5 million dogs in Thailand, of which about 730,000 are abandoned by their owners. Bangkok alone is estimated to have from 100,000 to 300,000 street dogs. Few have been vaccinated against canine diseases.
