What works for me here in Florida may not work for you. Always check with your vet to see what is working for your area. Read Read and do some more Reading on anything that you put on your pet. Also think of any health problems that you or any in your family may have that the product may end up doing you and your family harm. So always ask your doctor on his/her advise on the flea products. I hope this info will help you and your pet to have a happy and healthy life.
