With above average temperatures and rainfall this year, mosquitos are more prevalent. Therefore, heartworms are a bigger threat. Please be sure to keep your pets on year-round heartworm prevention and have them tested (blood test) annually to ensure they do not become infected with heartworms. We offer monthly chewable heartworm prevention and 6-month injectable heartworm prevention. Be sure to talk to one of our doctors to determine which is the best type of heartworm prevention for your pets and avoid the painful, costly treatment for heartworms should your pets become infected.
