I just had a question how often should my eight year old dog be tested for heartworm? She is in good health, so I do not assume she has this but I am curious. She had a test done about three years ago should I have another test done? We do not get an enormous amount of mosquitos here, but i just wanted to be sure.
Depends on where you live, in the USA , Heartworm is a serious common problem, in Canada we see alot less. Animals are tested every year regardless if neg last year or were on meds. There were only 2 hundred or so cases in Ontario. The clinic I work at I've never seen a positive animal,I've been there for 15 plus yrs. A huge percent of our clients are on Revolution. but at our Stoney Creek hospital theyv'e seen one positive animal. The test is so of course so you'll know the results but also, they need to be neg to go on the meds(preventative). If your not going on the meds than its up to you if you want to know. Preventative is easier than treating a sick animal that could die.
You should test at least once a year, especially if you aren't giving heartworm medication year round. I know for sure INterceptor guarantees that your dog will not get heartworm while you are giving it, but requires that the dog be tested annually to check for it. (stupid, eh?)
the clinic i work for has a policy that if you are on heartworm preventative year round with no missed months we will test every other year. we have seen two cases this year so far. both were shelter dogs that had been adopted.
