How many dogs per year get infected with heartworm? General Dog Discussions
I was just wondering an actual number of dogs that become infected with heartworm per year? I read somewhere that about 250,000 dogs are diagnosed with heartworm per year, which is actually pretty small, given the dog population is about 60,000,000 dogs in the US. So how many dogs really get heartworm each year?
