I would also double check his teeth could their be an infection where they removed the teeth? (down in the gums might be deep)
Glad they had some info that might help! My kids are all on holistic stuff so I always go that route to help with issues. When I go buy more food etc from DogGone Natural I will ask Kim (my holistic nutrionist) is she has any ideas too. I will probably go by there next week as I need to get Huly and Sadie more Olive Leaf.It's possible because I caught the little bitch doing it a couple of times, but her breath was no-where near as ghastly as his.
I got some "Plaque Off" (Made in USA, Liquid Form though) today from the pet store, it's supposed to help with bad breath and from what I've read, it's super-duper fantastic to erode existing plaque or keep new from forming, even though I don't expect mine to ever get it with the amount of bones they get & being fed raw. I hope this is the same brand as the powdered one everyone swears by and gets stopped by customs when they try to bring it in - bleedin' morons (Customs, not the peeps who want the best for their dogs) - as if it's a bio-hazard, pfft. This breath is a bio-hazard to put it mildly.
Sarah, let's make this our mission in life, to solve this stinky problem .... I really can't cope with it, it stops me from handling him and interacting with him as much as the others and that's just sad.
In the natural websites above, I found a parsley tea recipe that I'm certainly going to try ASAP and will grab some activated charcoal tablets from the chemist too. I loved those websites thanks Huly, they're so great for so many things
