If a dog has heartworm, how does the blood test tell what stage they have?


The blood test will only tell you if your dog is positive or negative for the antigens in the heartworms body. It will not tell you what stage of heartworm disease your dog has. If your dog is small, and has just a few worms, it can be severe, and your dog may be suffering from congestive heart failure. If your dog is large, and has only a few worms, he may not even have clinical symptoms.
