Client education is key
As with any new initiative, getting hospital staff on board to have these conversations with clients is key to success. This heartworm toolkit (sponsored by an educational grant from Bayer) will answer all your heartworm disease questions.
Excellent client education handouts are available for free from many resources, including the American Heartworm Society, the Veterinary Partner website (published by Veterinary Information Network), and dvm360. Use them in the practice to guide your client conversations, and send them home for unsure clients to review in their own time or to discuss with family members not present at the visit.
