John, bloody loose stool is a sign of inflammation in the large intestines (colon), she has colitis
. There are many possible causes for colitis, it will be difficult for me to determine the exact underlying cause without a hands on examination and some testing. But, common causes are: Dietary indiscretion, ingestion of a foreign body, parasites, IBS, infections, or even part of a systemic disease to name a few causes. The fact this has been ongoing for 1 month I would place parasites, IBS or part of a systemic disease high on the list of possible causes. This is what you can do:
1- Do not give things like Pepto Bismol or imodium. The pepto bismol will make the bleeding
2- Change her diet to rice (75%) and boiled boneless chicken
or ground beef (25%) until the stool is back to normal then wean back into a grain free diet like Taste of Wild.
3- Supplement with a probiotic (fortiflora), these are friendly bacterias that help with regularity and inflammation. You can buy this over the counter in any pet store.
4- Consider getting her dewormed you can buy Panacur (fenbendazole) in some pet stores or online (amazon.com). Give it once a day at label dose for 3 days, repeat after 3 weeks.
5- If after doing the above you do not see improvement within 24-48 hours, have her checked by your family veterinarian. If cost is a concern consider having her checked by your local ASPCA or Shelter where they often offer veterinary services at a lower cost. My goal is to provide you with excellent service – if you feel you have gotten anything less, please reply back. I am happy to address follow-up questions. Thank you for your business and I hope to work with you again soon!
