ABC15 talked with instructors at the Carrington College Veterinary Assisting program and they believe the Valley might be seeing more cases because of the type of new developments in the area.

Fortunately, veterinarians say the disease is easy to prevent.
"Ask for the vaccine," says Sandy Moore, the veterinary assisting program director. "Instead of letting it be an option, make sure you're getting it."
