Q. My puppy (12 weeks) is constantly itching and biting herself. I checked her for fleas but there doesn't appear to be any sign of them. Happy otherwise

A. Do treat her for fleas even if you don't see them as fleas are by far the number one reason for scratching and biting in dogs.
There might be something in her food that he is allergic to. Try a good quality grain free dry food (e.g. Orijen, Accana, Evolve or Canine caviar), transition to the new food gradually over a period of 10 days (every day put a little more from the new food and a little less from the old food). Keep her o the food for 2 months to decide if it helps or not.
If still none of those solve the problem, bring her to the vet for further investigation.
