Ask a Dog Vet and Get Answers to Your Dog Veterinary Questions
Hi, I can help you with your question today.
Based on your description, I'm worried that Zoey could have an obstruction, large number of intestinal parasites, or an intussesception (telescoping of a bit of intestine inside another adjacent region).
I highly recommend having her seen by a local vet immediately. Any of these conditions could potentially be fatal. I would start with a physical exam and x-ray. Hopefully these will be enough to give us a diagnosis so we can begin a treatment plan for her.
