Can Puppies Get Heartworms?
Yes. Heartworms are transmitted by mosquitoes—if an infected mosquito bites your puppy, your puppy is at risk of developing heartworm disease. Once infected, the heartworm larvae will develop into adult heartworms over the next 6 to 7 months.2 These heartworms can cause permanent scarring of the vessels and the lungs even prior to the dog testing positive.
