Leah had a nasty breath as a pup but as a deterrent I got her fresh breath spray from the pet store every time she ate her poo she got her fresh breath spray. Now we use pet toothpaste (Don't use human toothpaste there is something in it that makes them ill) and she gets her teeth brushed in the morning when I am brushing mine. You can get toothbrushes that fit on your finger or children’s toothbrushes work as well
