What Happens If a Dog Gets Fleas?

Quick Answer: Treat the dog immediately with a vet-approved flea treatment, treat every other pet in the household simultaneously, and treat the home environment — wash all bedding at high heat, vacuum thoroughly, and use a home flea spray. Treating only the dog leaves 95% of the flea population (eggs, larvae, pupae in carpets and furniture) untouched and the problem returns within weeks.

The Three-Part Treatment

  1. Treat the dog — vet-approved spot-on, oral tablet, or flea collar. Check with your vet for the safest option.
  2. Treat all pets — every dog and cat in the home on the same day.
  3. Treat the environment — vacuum all carpets, furniture, and pet resting areas. Wash all bedding at 60°C minimum. Apply a home flea spray that kills eggs and larvae.

Prevent Reinfection

Year-round monthly prevention is the most effective approach. A single missed month in summer allows full reinfestation. Wash pet bedding monthly at high heat as maintenance.

Wash All Bedding

Your dog's calming bed and blanket should be washed at 60°C during and after flea treatment. Both are machine washable.
