Rescued Belgian Malinois has special bond with terminally ill boy - Lucas Hembree is a four-year old boy who suffers from Sanfilippo syndrome, a rare genetic disease, as consequence, children with the disease suffer seizures and severe neurological damage and eventually loose the ability to speak, walk and eat. Lucas may not have many years remaining, but Chester and his wife Jennifer, want their son to experience the best quality of life while he can. So when Lucas began to have difficultly walking, Chester investigated getting a service dog to help Lucas. "I was told that a service dog would cost at least $15,000, and that Lucas wasn't a good candidate because of his deteriorating abilities and his behavior," Chester says. "I refused to accept this answer."
