Animal Welfare Professionals

I was wondering if anyone had some information to share that they share with adopters about intestinal parasites, especially when it comes to younger animals. More and more my group has had to deal with adopters who do not understand that we have started the deworming, but that they need to follow up with their vet for further deworming. We will get a call a few weeks later complaining about how their pup or kitten has worms, and while you said you dewormed them we don't believe you! kinda situations. So mostly I was just wondering if anyone had any great examples of literature or 1 pagers they send home.

Thanks,
