When we see diarrhea, mucus and blood those are signs of inflammation in the colon (colitis
). Your dog has colitis, possible causes could be infections, ingestion of a foreign body, dietary indiscretion, auto immune (IBS), parasites or even part of a systemic disease to name a few causes.
To determine the exact underlying cause your dog is going to need a fecal analysis, xrays and +/- blood work (chemistry profile and CBC) by your family veterinarian. In the meantime, this is what you can do:
1- Do not give things like Pepto Bismol, it will make the bleeding
worst. Start him on Pepcid AC (famotidine
) 0.1-0.2mg per pound body weight every 12 hours. You can buy Pepcid AC over the counter in any pharmacy.
2- No food or water for 6-8 hours. Then, introduce small amounts of water followed by a diet of rice (75%) and boiled boneless chicken
or ground beef (25%) until the stool is back to normal then wean back into regular diet.
3- Supplement with a probiotic (fortiflora), these are friendly bacterias that help with regularity and inflammation. You can buy probiotics (fortiflora) over the counter in any pet store.
4- Follow up with your family veterinarian.
Hope the above helps, if you have additional questions I will be glad to answer them.
