It is necessary to have a dog when living in the Philippines because of all the breaking and entering that occurs. They are not a sure-fire theft deterrent but nothing ever is a sure thing. And when the dogs you have to protect you property are out and about they sure aren't going to be protecting your property.
So who let the dogs out? The Filipino who owns them!
None of these dogs are strays. They are all out on the prowl because either the owner did not secure the fence or opened the gate to let them run about. Why would a loving dog owner not secure their fence or purposely let their dogs out to run about in the street all day? They wouldn't. That's just one way Filipinos let the rest of the world know they are not kind and loving towards animals.
Loose dogs are a menace. They dig through the trash and spread it all over the neighbourhood. They get in the way of cars. They poop everywhere. They growl and bark at passersby. They breed uncontrollably. Their bodies become mangy and disease infested. They bark all day and as they stroll about they set off all the other dogs who are secured behind fences.
But who cares right? If you don't like it leave! Certainly Filipinos must like having a country full of loose dogs on the prowl. Otherwise they would secure their dogs and their fences.
