The last 6 months or so Lloyd has had horrible bad breath and I cannot figure out why! I have been brushing his teeth every day (once a day), and at night all the animals get this blue gel stuff the vet gave me put on their gums that is supposed to help clean the mouth. I also use this spray that is supposed to help with plaque and tarter build up (and it does seem to work well). They raw meaty bones a couple of times a month too. I switch foods like every bag and it doesn't seem to matter what food he is eating. Any idea?
