My dog has gleas and she weighs 90 lbs. I gave her the large dog dose of front line plus, but it is not working can I give her a small dog does on top of that without hurting her?

I would not recommend using Frontline Plus for dogs living in Florida. Frontline has been around a long time and it seems as though fleas are becoming resistant to it . I suggest you try one of the new oral flea/tick pills (Nexgard, Bravecto or Simparica). You can go to any of the VETCO vaccine clinics inside Petco stores to consult with the vet and get one of these products. Take your dog with you. Here are the upcoming clinics in your area.

Remember, you also need to treat the house and the outside environment in order to get the fleas under control. Also, all pets in the house should be on a monthly flea prevention.
