Hi Just had my little Jack Russell Lola's teeth cleaned while she was in getting a few lumps removed. I want to use Plaque Off (seaweed based powder that is shaken over your dogs food) but I already use salmon oil in Lola's and her brother Harry's food once a day so would be scared of mixing the two together even if they arent served in the same portion of food. Does anyone know if its safe to do so? Many thanks in advance for help provided.
