Hello I am new to this forum, I joined to ask about my Yorkie named Baby

. She is 4 years old and 8lbs. She had very soft poop about 4 days ago, she seemed find afterwards and then unfortunately my mom gave her canned Salmon, I dont know if it was the salmon that started her up again or not but she has the runs now. She has to go several times a day and she has been making mistakes in the hosue which she never does b/c she cant help it.
She is acting normal and eating normal. I havent given her the soft food I usually do yet today in fear that she will have to go. She has her hard food down, which she will not eat unless she is REALLY hungry. I read about giving her rice and some canned pumpkin.....will that help? Or boiled chicken?
Thanks everyone
