Dogs should be tested before being put on preventatives.  We feel that the tests on cats do not result in clear enough results, for they detect exposure to heartworm, not whether the cat actually has an active heartworm infection.  Dogs are much more easily infected with the heartworm then cats, although we do not know why this is.   If we do not test a dog before putting on the preventative every year, an infection could be missed until the dog is showing signs.  Treatment on a dog who is symptomatic is much more difficult and more likely to be deadly than a dog whose infection is caught early.
