What dog food and toys should Samoyed, who is three months old, eat?

"Puppy dog food" should be fine. You can buy it in a pet store. But at that time our dog didn't eat dog food. They ate small soft biscuits (hard) bought from the supermarket. They must be crushed before feeding.

Dog toys can be bought at any age. If you are three months old, give a rolling ball (not too big), preferably a slightly hard toy, which can grind your teeth to prevent the dog from biting the furniture again.
