Why does my puppy keep getting round worm? And how can I prevent it? He’s been getting de-worming shots with his puppy shots every 4 weeks since 6 weeks old (1 more puppy pack to go this Sunday). He’s our only dog and went to the dog park for the very first time this past Sunday and once more on Tuesday.

Just in case, make sure your veterinarian is confirming the presence of roundworms (tapeworms can sometimes be confused for roundworms). If tapeworms are present, Koda will need a special medication. The two most common reasons for persistent infection with roundworms are not yet clearing the infection he was born with (yes, they can be infected in uterus) or your yard is contaminated with roundworm eggs (one study showed roundworm eggs remained infective for 20 years). Continue with the routine dewormings and start him on a heartworm prevention like Interceptor. You should also alert your vet who may change the deworming schedule. Remember that these worms can also spread to humans so make sure to practice good hygiene.
