Do indoor dogs still need flea and tick prevention?

Fleas and ticks do not require extensive outdoor time to hitch a ride, a single walk around the block, a trip to a friend's garden, or even contact with another pet that has been outdoors can introduce them into your home, where fleas in particular can then establish themselves in carpets and bedding.

Because an indoor dog is not obviously exposed to fields or woodland the way an outdoor working dog might be, owners sometimes assume the risk is negligible, but even brief daily walks in a typical neighborhood provide enough opportunity for exposure over the course of a year.

Your vet can weigh your dog's actual exposure, how much outdoor time, what kind of environment, whether other pets in the household go outside more, against regional parasite prevalence to recommend whether year round prevention makes sense or whether a lighter approach is reasonable.

If another pet in your household, particularly an outdoor cat, spends significant time outside, that pet can bring fleas into the home environment even if your indoor dog never leaves the house directly, which is another reason to discuss household wide prevention with your vet rather than considering each pet in isolation.

Visitors' pets or a boarding stay at a kennel, even briefly, are other common but easy to overlook routes for an indoor dog to be exposed to fleas, worth factoring into the overall picture when discussing risk with your vet.
