I practice in Canada and we see a few cases of heartworm each year (unlike the great number of cases that are seen in the southern US). I work in a practice that has a lot of clients who are diplomats and do a lot of travel to other countries, often with their pets. I was just wondering if heartworm is something that is seen in the UK? Or, if you are from another country, do you know if heartworm is seen there? Thanks!
