In this guide (6 steps)
  1. Step 1: Know the signs

    Frequent scratching, chewing at the skin, red bumps or hair loss around the tail base can suggest fleas. Some dogs show few signs, so regular checks help.

  2. Step 2: Gather supplies

    You need a fine-toothed flea comb, a white towel or paper towel, a small bowl of soapy water and treats. Work in good light.

  1. Step 3: Comb key areas

    Have your dog stand or lie on the white towel. Comb along the back, the base of the tail, belly and armpits. Dip the comb into soapy water after each stroke to trap anything collected.

  2. Step 4: Do the wet paper test

    Tap any dark specks onto damp white paper. Flea dirt turns reddish-brown as it dissolves because it contains digested blood. Ordinary dirt stays dark.

    Good to know: Check every pet in the household; fleas easily spread between animals.

  3. Step 5: Talk to your veterinarian

    If you find fleas or flea dirt, ask your veterinarian for a suitable treatment for your dog's age, weight and health. Never use cat or dog products on the wrong species.

  4. Step 6: Treat the home too

    Wash bedding on a hot cycle and vacuum floors and furniture often. Follow your veterinarian's advice on ongoing prevention.
