Are you just fed up with trying everything you can possible find for your Doggie breath, and it just seems that nothing seems to work. Well I have your last and final answer... Being a breeder for over 10 years and trying different products on many of my dogs. I have found the answer........... The best way to avoid bad dog breath, and teeth decay is by maintaining weekly mouth care . Look closely for any loose teeth, sore and infected gums, and rotting tooth sockets.
