Does my dog have fleas?
If you think your dog has fleas, there's a very easy procedure you can do to find them...
How to find fleas on dogs
Take a small sheet of white paper (kitchen towel works best), and moisten it, hold it near the base of the dog's back, and brush or scratch him vigorously in the same area holding the paper close by. Black specs of dirt/dust will fly on to the paper. Any that dissolve in the water on the paper to leave a reddish smudge are flea faeces containing blood.
