Following the earthquake and tsunami, the Japanese people need and are receiving help from individuals and agencies around the world. The pets need help, too.
Global Animal. Org On their site they list several groups that are already on the ground in Japan making a difference.
World Vets. I only recently discovered this organization which seems to be similar to Doctors Without Borders. I'm impressed with what I've read about them.
ARK Animal refuge Kansai is also accepting donations to help the Japanese animals. They accept Paypal making it quick and easy to donate.
Lucky Dog Treat Company is donating 50% of their sales for the remainder of the month to World Vets disaster relief. Lucky Dog is an Etsy shop, so while helping dogs in need, you're also supporting a craftsperson. It's a win-win!
