Not sure if this should be under feeding??? Sorry if it should be

Can I give my 9 week old cocker raw hide type chews. I gave her one which she was loving until I read 'Not for puppies under 3 months'. It looked like it was going to keep her quite for a while

, but not sure if its too hard for her teeth/gums. I won't give it to her again until she's grown up more - unless anyone can tell me differently or suggest something else, but it seems all puppy chews are for 3 months+.
