re: Dog dental cleanings, legit or scam?

Our vet suggested it on an annual checkup/shots. The next year, she asked me where I took her for a dental cleaning, that her teeth and gums look fine.

I didn't take her anywhere, just started saving the pork rib bones and giving them to her, and also the blade bone when I cooked a butt. She was happy and her teeth were good.

Now there is a risk that the shards can hurt her, but she made it about 12 more years with no problem.
