April is National Heartworm Awareness Month. Heartworm can be a danger to all cats, dogs, and ferrets regardless of amount of time spent outdoors. Mosquitos carry early-stage heartworm and easily transmit heartworm disease from animal to animal. Though heartworm is dangerous and potentially fatal; luckily, heartworm disease is preventable! As always, feel free to reach out to Pacific Veterinary Clinic staff with any questions about heartworm disease, heartworm testing, or heartworm prevention!
