When Is The Right Time For A Puppy To Take The First Bath? Generally, newborn pups donât need to be bathed up until they are about three months old, and most canine shampoos are for dogs which are at least 3 months old, however, you can still bathe younger puppies if they are visibly dirty or smelly.
For the first month or so, puppies can't regulate their own body temperature, and they (especially toy and tiny breeds) can get chilled pretty quickly... so a puppy bath is not a good idea during that time, and a quick 'sponge bath' is much better, and safer.
