Hi, I have a 6 month old Yorkie mix girl weighs about 3.5lbs. A well-meaning family friend gave her table scraps (roasted turkey and seasoned chicken and cooked vegetables) against my wishes over the holidays ... and you know the rest!
She was listless and had almost liquid poop all day Xmas. She vomited a little also (2x's) towards the end of the night.
I ended up letting her go dry (no food for 12hrs) with only access to fresh water b/c I didn't want her to get dehydrated. The next day (noon) I gave her about a tablespoon each of cooked ground beef and plain boiled rice mixed together. I fed her the same amount every 2-3 hrs until about 10pm. By the end of the day her stools started to firm up.
The following day I fed her about a tablesp of her usual dry kibble (Royal Canin) . There was no bad reaction so I fed her the same amount every 2-3hrs. By the afternoon, she was making soft stools. She is energetic and playful and doesn't seem too bothered by the whole thing.
I didn't use Pepto because I was scared to give the wrong amount. I'm not sure about using it as I think every dog is a little different even within the same breeds. If the rice and beef hadn't worked I was planning to give her some plain yoghurt. If no home remedies worked, then it would have been off to the vet! (Trying to save some money on Dr., but not wanting to put pup's health at risk). Good Luck!!
