Help me get this dog out of Thailand

tWhile on vacation in Thailand I came across this dog in horrible condition. He lost the use of both of his back legs due to a motorcycle accident and the owner has done nothing for him. He drags himself around by his two front legs to get around, leaving his back legs extremely raw from the friction of the ground. I've contacted a bunch of rescues I'm the area but they are all full/don't have the resources for such an extreme case. Please help me raise money to bring this poor guy back to Canada where he can get the vet care he needs. He's less than a year old and there's no way I can  just let this go without trying to help. I'm not exactly sure how much everything will cost but i think 4000 will cover the initial vet costs/travel fees to get him out of Thailand. Thank you so much!

EDIT: so I got a quote from the vet for how much everything will cost and unfortunately I underestimated the costs by about 1000 dollars so I raised the funding amount to compensate for the added expenses.

Thank you!
