"I took them straight to the vet and she told me that the little boy was not doing too well (malnourished and dehydrated ) because whatever they had found to eat while they were homeless, he always let her eat first.

INTERESTING FACT ABOUT YOUR PET: Nearly 80 million U.S. households have a pet, and 42 percent of those households have more than one, according to a 2015-2016 survey by the APPA. There are 77.8 million pet dogs in the U.S. and 85.8 million pet cats.
"He was a rock in our family and always held down the fort," Lambert added. "He lived his life with no fences. The way we all want to live."

Lambert has long been a proud rescue dog parent, as well as other animals. She regularly shares photos of them on her social media.
