Veterinary advice on how often to worm seems to vary; once Molo was 6 months old, my vet advised every 6 months with Panacur was sufficient
However, after reading several posts on here, I increased this to every three months - especially as I have a young daughter, walk Molo in the country, and feed him raw
I used to use Advantage de-flea spot-on every month; but now I am supplementing his diet with garlic, I only use a spot on in the summer, about once every 6 weeks or so
