Thanks. I thought that if it was the first dose and she had not been tested she might have parasites that could cause symptoms. Sorry she had the infestation before, I agree the sight of the worms is gross!
You are not alone in the poop inspection, LOL! Especially amusing to any onlooker is the dark night examination with a flashlight

If she has been taking the Sentinel before I would not think giving the appropriate double five pound dose for a nearly ten pound dog would hurt. But who knows? If she is ten pounds then a five pound dose might not be enough.
Good to hear she is more herself now. Praying tomorrow she will be 100%.
Sleep well
