I found your list from Banfield Pet Hospital very interesting - I was reading on the website that many vets are already reporting seeing as many cases of dogs infected with heartworm up to May of this year as they saw in the whole of 2011. I hope this encourages more pet owners to get their dogs on a preventative program - it is a subject I feel passionate about - especially as the shortage of Immiticide (made by Merial) has resulted in many infected dogs having to wait for treatment until stocks could be shipped in from Europe.
