I know my view is not popular, and I usually just keep it to myself, but frankly, if all the shelters would give the needle to every "unadoptable" dog as soon as it comes in the door, (well, as soon as they were legally allowed to with strays) they would have a lot more room and money to take care of the ones that stand a better chance of finding a home.
I once read a statistic that said for every dog that gets adopted, 7 others are euthanized. I'm not sure if 7 is the true number, but I think it's safe to say that there
is definitely a number, and it's high. The point the person was making was that when you pick out a dog, you should not feel sorry for the worst prospect in there and adopt it, because that means a healthy dog with a better temperament will get put down instead. So I think it makes sense for shelters to not waste their space on the unadoptables. And if transporting the cute fluffy adoptables to areas that have a shortage helps to save more of the little ones, that's better than the little cute fluffies getting put down in one state when someone in the next state can't find any.
I think fewer dogs would languish in shelters if money weren't wasted on huge vet bills for the ones with serious or chronic health issues, and if the ones with obvious aggression, and yes, even high anxiety issues, were put down as soon as that could be determined. That would leave the better quality dogs for people to choose from, and then there would be fewer returns because the new owner would have a better chance to succeed with their new dog.
Guess I better prepare myself for all the abuse that is now going to rain down on my head.
