Finding Proper Medical Care Can Be A Challenge.

Even as the arrangements are made to send animals to safe and secure places, one of the biggest challenges the organization faces is finding a veterinarian that's close by. Misseri told Newsweek veterinarians may be as far as five to ten hours away.

But no matter what the challenges may be, Misseri said it's worth it because it means so much to the service members involved.

"I've talked to many service members who didn't know there was an option that they could bring a dog or cat back home and they left them behind," he said. "They can develop PTSD over it, they can fall into a depression and they feel like they have betrayed the animal."

Misseri also notes that if a military camp has to move to a new place, service members can't bring the animal along. Leaving the animal behind, he says, can be "devastating."

"When we get a message from them, we jump into action and do everything we can to make it happen," he said.
