Caught early, a flea problem is easy to fix. Here are the signs of fleas on dogs and exactly what to do next.
Early warning signs
Watch for excessive scratching, biting or licking (especially at the base of the tail), restlessness, and red or irritated skin. Fleas prefer the warm areas — tail base, belly, and behind the ears.

Confirm it's fleas
Part the fur and look for fast-moving dark specks (adult fleas) or 'flea dirt' — tiny black flecks that turn reddish-brown on a wet paper towel (that's digested blood). A flea comb helps you check and catch them.
Act on all fronts
Treat your dog with a vet-recommended product like [NexGard](/products/nexgard-chewables-for-dogs), and treat your home — wash bedding hot, vacuum thoroughly, and repeat. Fleas live mostly in the environment, so skipping the home lets them return.
Prevent the next one
Once cleared, stay on year-round prevention. Consistency is what keeps fleas gone. If your dog has pale gums or seems weak, see your vet — heavy infestations can cause anemia.
