AN ABSOLUTE MUST IN THE FIELD, INSTANT FIRST AID FOR YOUR HUNTING DOG! As with EMT Gel, EMT Spray prevents scarring and “jumpstarts” the healing process, slows bleeding, reduces pain, itching, and the chance of infection by forming a protective barrier over the wound. EMT Spray also contains Bitrex™ to help deter biting and licking of the wound. 1 oz spray.
