If you are using Frontline or Frontline Plus and are using any human shampoo, Dawn, or any flea shampoo you are washing the Frontline off and it will not work. You need to use a mild aloe/oatmeal good pet shampoo recommended by your vet to keep these products working like they are supposed to. As was posted early, if they have flea bites, are allergic, it will take them a little while to feel better. Sometimes they need antibiotics and antihistamines to heal. |
