At what age do puppies lose their baby teeth?

At around 4 months of age pups begin loosing their milk/puppy teeth. Don’t be alarmed if you don’t find any laying around as it’s normal for them to swallow them and pass them without you ever knowing. Unless the baby teeth refuse to come out so the adult teeth are coming in along side them, there’s no need for concern. Your pup will very likely be doing a lot of chewing during this time, so provide things they can chew on to save your shoes and furniture legs. A small amount of bleeding is normal when they lose a tooth, just like when a human child loses theirs.
