"A study on “Heartworm in dogs in Canada in 2010” published by the Ontario Veterinary College’s Department of Pathobiology at the University of Guelph has revealed a 60 per cent increase in the number of dogs in Ontario with heartworm since the last study of its kind was conducted in 2002.
The Canada-wide study showed that 564 dogs tested positive for heartworm in Canada in 2010; 431 of those dogs were located in Ontario (that’s over 75 per cent of the total). Also of concern is that eighty per cent of animals that were found to have heartworm had not been on a heartworm preventive medication. In a few cases, pets that had been receiving heartworm preventive medication also tested positive for the disease; the most common reason for this was that the pet owners indicated they had forgotten to give their pet the preventive medication at the prescribed intervals.

What should be of concern to the OVC is that 20% of he dogs WERE on heartworm medication...

Did you miss the next sentence where the owners admitted missing doses?

I did...that puts it in an entirely different context - animals with heartworm being given the preventative medication - which would be a concern. My fault - read over it too quickly.
