My partner and his parents helped for many years dogs in thailand, and did alot of neutering however some times it's fairer to just cull. It's horrible but having seen pictures of what they saw and dealt with was horrible. The volume of dogs they would get neutured in a day was amazing. The vets were fantatsic (Met the main one when I went over, lovely chap, basic equipment everywhere but if he was in the UK my dogs would be with him!)
Sometimes it's not fair and at one point the government un-did all the hard work done with the temple dogs.
Bringing just one dog back doesn't do ANYTHING. It still leaves many entire dogs and bitches mating and having puppies. Such a sad state of affairs.
And it's not just the strays. Puppy farming is a big business over there, pedigrees go for alot of money (in comparison) but these dogs end up chucked on the streets.
Partners parents had 15 dogs at one point living with them, they moved up north and took 7, then brought 2 back to the UK with them, one died, one PTS as due to age and health and others rehomed with friends.
You have to remember it's compleatly different over there and just finding a dog and bringing it back off the streets takes away a home for a dog in a UK rescue. :(
