Regional and local temporal trends in the prevalence of canine heartworm infection in the contiguous United States: 2012–2018
Abstract Background Canine heartworm disease is a potentially fatal disease for which treatment is financially burdensome for many pet owners. Prevention is strongly advocated by the veterinary community along with routine testing for infection during annual wellness examinations. Despite the availa...
