What your pup would have received and ongoing treatment.
Intestinal Worming treatment has been administered at two, four and 6 weeks with Drontal then at eight weeks with Advocate & Virbac (Tape Wormer) Advocate is a monthly topical treatment that prevents heartworm, controls intestinal worms/larvae, stops fleas feeding within 3-5 minutes.
I recommend a monthly dose of Advocate as this covers fleas, worms, ear mites and heartworm and is very simple. I just administer on the first of each month as it is easy to remember. Advocate is quite expensive but can be purchased online from Oveds.
