I think my dog has it now...

I think I infected my dog with this. I got her as a puppy, and she had no symptoms. Then about 2 months later, she suddenly developed very bad breath that was coming from somewhere internally it seemed like. She also got a runny nose that is constant just like mine, and started pooing multiple times a day (like me). Also has low appetite. I never kiss her intentionally on the mouth, but I kiss her nose a lot. And she has licked me on my mouth and a few times IN my mouth (much to my disgust), and she's also eaten a lot of my food I've had bites of and has drank straight from my water glass (don't worry, I don't drink after she does this lol), etc... So I am worried that I gave her the infection. I am taking her to the vet next week for testing.

Your dog may have more than you expect. It's difficult to control what your dog do in the park, smelling and probably licking other animals' "byproduct".

I think H. pylori is the least you should worry about from your dog. There are far more dangerous bacteria out there.
