My little girl didn't show any interest in eating yesterday - not typical at all of her. She's usually a piggy & will eat anything. She seemed a little lethargic & she vomited some clear saliva. When I picked her up so she wouldn't step in the vomit, she was trembling a little. I got scared & took her to the vet. She's not dehydrated/hypoglycemic, but my vet put her on Metronidazole in case she had a bacterial infection. We also changed her probiotic to a chewable vs. powder. She's eating now.
Here's the thing...at the vet last night, she let out a little poof of really stinky gas on the exam table. And now, she's had REALLY stinky butt ALL DAY

I called my vet, but he's in surgery. I read on an old thread that it's okay to give them children's Pepto or a liquid for gas. The thread was from 2009. So I'm wondering if that would still be okay. Has anyone given their pup over the counter people medication for gas?
She is eating today & seems back to her old self. I did give her a dose of the Metronidazole early this morning. I'm running out to get blizzard supplies & figured I'd grab some Pepto or something just in case. Thanks!!
