Infant yorkie puppy when to introduce solid foods? At what age? Best brand of food?

Most puppies start to become curious of different types of food around 3wks of age.

I suggest to start your puppies on a high quality puppy food. I'm a fan of pro plan puppy. It produces nice, fat, healthy puppies.. and they like it too!

Some people suggest to soften the food for the puppies to make it easier for them to eat... I've welped a lot of puppies and found that being harder to introduce than just offering the hard kibbles and letting mom introduce it.
