It really depends on
what product you used. If the active ingredients are from the same group of
insecticides, there needs to be a gap of at least three weeks between
treatments. However, if the active ingredients come from different chemical
classes then Frontline Plus can be safely used. Either way please wash your dog
before the treatment. After the bath please allow at least two days until the
flea treatment, this is the time the skin needs to regain its natural balance.
When using Frontline Plus it is recommended that emollient shampoos be avoided
because they reduce the product efficiency. Also when using topicals please keep
your dog away from water for at least two days, this is the time the product
needs to be fully dispersed all over the pet’s skin.
Always read and retain the
