Thanks for the ideas everyone.
I hate the smell of cow hooves too, I think they smell like vomit but this smell is still different. DEFINITELY metallic.
And agreed on the “smell it when he yawns” thing–he just licked his lips next to me and I caught a whiff.
I’m goign to explore the ulcer idea. Had tapeworms and the works when I found him but his gut is clean now. Maybe probiotics would help…I might try the yogurt thing, I don’t think any of my crew would object to that.
I have a toothbrush and paste and (another bad mom comment) they only get done about once a month or so–but HIM I do once or twice a week, although it never helps the breath stench.
