How expensive is it to treat a dog that is heartworm positive?

There are a few dogs that i am interested in adopting but the ones I have seen are heartworm postive. Is that extremely expensive?

It depends on several things:+ The infestation itself. If it's low grade,the treatment is less expensive...+ The area in which you live.+ Individual vets... some are more expensive and some are less... Talk to your vet and ask. This is a very treatable disease and you shouldn't skip the dogs that are sick. Those dogs could all make great pets and do deserve a chance.

Talk to your vet, they can even treat dogs that are heartworm positive with a heartworm prevention medicine nowadays avoiding the costly heartworm treatments of the past.
