Arlo finished puppy classes and goes to doggy day care 2 to 3 times a week.  He loves his new life with his older “brother,” Jax, who weighs in at a whopping 23 lbs! The two love playing together. Arlo is from a colony of dogs with Batten Disease, a fatal, inherited disorder of the nervous system that affects dogs and young children. Arlo is unaffected. Children suffering from Batten disease become blind, bedridden, and demented; they typically die in their late teens or early twenties. His research family is studying gene and enzyme therapies for affected dogs, and an enzyme therapy to treat affected children is currently in clinical trials.
