Bones. Yes or No? Which ones?

Hello! I’m a new puppy parent to a now 7 month old Cavapoo.

I’m seeing a lot on contradicting information on bones (whether to offer, what types).

Seems there is a risk of eating a shard or breaking a tooth? But dogs love bones and it seems ancestral.

What is the consensus on which ones are safe/worth the risk? (Obviously no cooked chicken bones but which are SAFE). Unrestricted access or only while I’m home? Only as an activity or for hours a day?

She deserves a way to self soothe IMO but I want her safe and healthy.
