Welcome to the forum Tipsey.
Hope we can get some ideas for you.
What type of food is she on - dry or canned? Has she had any recent blood or urine work done? If so was there any issues?
When you were using the Restoralax, how much were you using per day? How heavy is she?
When you say she "runs around the house with poop falling", what exactly do you mean? Is it hanging from her anus, or is it like a diarhea, or is it hung up with hair in the digestive system?
Has she been seen by a vet in recent months, and is your vet just a standard vet or integrative?
Some answers to these questions might help the members to help you.
I'll see if I can come up with some ideas to look at.
