TOMBALL, Texas (KTRK) -- For years, Abandoned Animal Rescue in Tomball has saved pets left to fend for themselves on the streets, or those no longer wanted by their owners.Some of the animals that have passed through their facility in Tomball could tell stories of terrible cruelty.Monday morning, a cruelty case landed close to their front door, or front gate.Surveillance video shows a pickup truck passing the building once, before returning, then pulling into the driveway outside the locked gate. A man gets out, walks to the other side of the truck, and returns. After the truck leaves, a small shape can be seen emerging from behind a trailer.It was a small dog, and it was limping. The rescue's volunteers said the small black terrier had been thrown over the fence.The dog was limping from either a hard landing against a small trailer near the gate, or perhaps it had been hit earlier by a car. Either way, the dog was badly injured.The dog was found a couple of hours later by rescue volunteers arriving for their morning shifts."The volunteers said he was in a lot of pain and wouldn't get up," said Karen Pitcock, a member of the rescue board of directors."We took him to a vet, who said he had a fracture. I can't believe anyone would be so cruel to toss an animal over the fence, injuring him or making an existing injury even worse," said Pitcock.The dog, believed to be 2 years old, was given a new name- Jake. Wednesday, he had surgery at BluePearl Specialty Pet Hospital at Willowbrook."It's usually vehicular trauma, but being tossed over a fence could also do this," said BluePearl surgeon, Dr. Justin Payne.For the rescue, Jake's story didn't have to happen."All they have to do is come inside and talk to us. If we can't take the animal, we know other rescues that can," said Pitcock.Abandoned Animal Rescue is raising money to help with Jake's medical expenses. Of the $2,500 surgery costs, which is a discounted rate, only $170 have been raised.If you're interested in learning more about the rescue, or adopting Jake after his recovery, or helping with his medical bill, go to aartomball.org , or on Facebook at AAR
