Heartworms are contracted through mosquitos—they bite a dog that is infected with heartworms and
transfer
the microfilaria to another dog. This is why all dogs, especially those in warm Houston climates where
mosquitos are prevalent, MUST be on a strict schedule for a monthly heartworm preventative. Heartworms
are
NOT contagious between dogs that are on a preventative.
Please do not let a heartworm positive status deter you from adopting a dog! They are all so
deserving!
AJL will cover all expenses relating to heartworm treatment, even after a dog is adopted, until the dog
tests negative. Please note, the adopter will be responsible for monthly heartworm/flea
preventatives and
any other vet expenses unrelated to heartworm treatment post-adoption.
