Rowan Sanderson sits down with Dr. Brendan Clarke, Co-Host of Raw Pet Medics and President of the Raw Feeding Veterinary Society (RFVS) to discuss Lyme disease in dogs. Lyme disease is an infectious disease caused by a type of bacterium called spirochete, which is carried in the digestive tract of ticks. The ticks regurgitate materials, including this bacteria, into the skin of whatever they are feeding on.
