Well the box doesn't say if I should bathe him first or not. It does say that it lasts for one month. Well suppose I bathe him every two or three weeks does it stay active? I also saw that some of you did half a dose. Can I see some thoughts on this issue? My puppy will be 5 months in a few days and weighs about 3lbs 4 oz. The box the vet gave us says for puppies and dogs up to 22 lbs. Is that the appropriate product? Thanks for your help.
