I do not think it is a good sign that her Yorkie is having this many Bowl movements , + the ones he is having is the color of the gum

AND the vets she has talked to have told her that her pup is going to be fine? This is toxic! Isn't her dog still at risk? in danger? & if i am clearly reading the posts right, her pup has be alone most of the day? Mom has been at work? But was able to check on him during the day?
I'd be a nervous wreck if this was my dog> I see red flags all over the place. How long is the puppy in danger? I beleive it is too late to induce vomiting, and will the pup show extreme distress within hrs? days?
Is ther eanything the owner can do at this point for her Yorkie?
