Thanks Wylie's Mom for your input. I'm finding the manufacturer of Heartgard (Ivermectin) tablets for dogs up to 25 lbs. are out of stock and on back order, so I guess if I am to resume heartworm preventative, I have to use my Interceptor. I will see if I can speak to the Vet today (Sun.) for advice.
