Generally, newborn pups don’t 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.
Choosing The Right Shampoo
The label should provide all the necessary information, like the age at which the shampoo is safe to use on your pooch.
Most dog shampoos on the market aren’t safe for pups under 12 weeks old, but if your ball of fur got really dirty while exploring the wonders of the world, deodorizing shampoos are safe to use.
Just like with us humans, their skin types can vary, so if you see that your pooch has dry or sensitive skin, buy the shampoo formula for dry and sensitive skin, etc.
Newborns don’t usually get as dirty as older puppies do, since they are not running around playing and exploring. But, if they do, and the mother is not around to lick them clean, it is safe to wash them gently with a warm, moist washcloth.
If you wash a very young puppy, it is important to make sure he is warm during and after cleaning.
