What can I do to treat my dogs bad breath?

For two weeks she has rank breath. I tried parsley in her food. Brushed her teeth. Now I am at a loss.

brush her/his teeth jus like you would brush your teeth she may not like it but it works though

Dog has really bad breath and Dentabones aren’t helping.?

Consider changing the diet, or heading to the vet for a deep dental cleaning.
