My animals get frontline....which has not worked recently....I found 1 flea on my Fergie. I ran to the local pet store and bought an all natural flea shampoo! Bathed all the animals including the cat. Found another flea 2 weeks later. We do not have any carpet and the dogs are only allowed in the living room and kitchen. I just can't seem to get rid of these buggers. They are all up to date on the bio-spot treatments. What should I do???? Help me please please please!
