Hello all.  Does anyone out there know what the proper dosage is for a
ferret when using the Frontline top spot liquid?  Someone told me it was
half a vial for one ferret but I am not sure and neither is my vet.  Also,
once you open the vial, can the remaining liquid be used the next month?
Or should I just throw it out?  Thanks.
