That is frightening, especially in the South because so many of the dogs coming into shelters from the streets test positive for HW disease. It's not uncommon for golden rescues here in TX to treat 50 or more dogs annually for HWs before they can be adopted to families.Thanks for posting this. I'm glad to hear it too, but it's not enough. The last HW positive dog that came into our rescue was scary. They had to get immiticide from 4 different vets in order to treat her. I don't know what will happen with the next one.
I know that I will ALWAYS give HW meds all year round. It's just not worth the risk no matter where you live, IMO.
