So about a month back my sister got a dog, Sasha. Sasha is short about Missy's size weighs 52 pounds. She looks like a Pit/staffy mix maybe, because she's short, huge head, short tail. She is under weight you can see her ribs. She only eats a cup of food a day. Piper eats 3 cups and Missy 1 1/2, Sasha should be eating more. My sister, Michele is trying to get her to eat more but she won't. Well Michele just called me saying Sasha has had diarrhea and is not eating. She said her ribs are showing even worse than before. I suggested rice to help stop the diarrhea is there anything else she can do? Michele is also having to take her out every 2-3hrs even at night. She is hand feeding her to get her to eat a little bit.
