Just to answer a couple of your questions -- if the dogs are friendly, the pilots will take them out of the crates for a drink/walk/potty break. Then, the crates are loaded up into the next plane and the pups are on their way.
Thanks for saving these dogs -- the dog population in Los Angeles is staggering. Please give PNP another chance to help you get them to safety.
