Why is my senior Rottweiler straining to poop with chronic diarrhea?

Thank you for submitting your question regarding Remi. In the bloodwork that was run, did it include GI specific testing such as cobalamin, folate, PLI and TLI levels. These are values that will give information such as the location of GI disease (small intestine vs pancreas) and treatment options. I typically do this planel in conjunction with an abdominal ultrasound. This information with the ultrasound can give insight into conditions such as inflammatory bowel disease, pancreatitis, exocrine pancreatic insufficiency, food sensitivities or as you mentioned cancer. The anti-inflammatory properties of the antibiotic she was on could help even with a tumor in GI tract, but there are so many other causes of diarrhea that would respond as well. I think it is worth pursuing further bloodwork and the ultrasound. If you can get a diagnosis, then a treatment plan can be developed. I hope this information helps!

If you have not done a good trial already, I would recommend a diet such as Royal Canin Ultamino and feed this for at least 4 weeks and see if this makes a differencr. If after the diet trial there is no difference, I would recommend adding in a probiotic such as Purina fortiflora which can be found online or at your local pet store. If the diarrhea is still there, I would recommend an abdominal ultrasound. If this is inflammatory bowel disease, Bonnie may need to be on drugs such as Budesonide and Azathioprine. I hope this helps guide you in the right direction. Please let me know if you have any other questions or concerns and I would be more than happy to help you further.

There are many different causes for chronic diarrhea in older dogs, none of which are usually great news. The best and shortest list I can provide you is the following: lymphoma of the GI tract, inflammatory bowel disease, lymphangiectasia, liver disease, gastrointestinal parasites, and/or nutritional deficiencies like lack of vitamin B12. Since you have mostly ruled out GI parasites, I would recommend beginning to investigate the possibilities of some of the others I have listed. In order to do this, you will need to obtain some blood work with your vet (baseline plus the B12 test), then work out whether or not he/she can do ultrasound / endoscopy to rule in / out the other conditions I have listed. Hope this makes sense. Best of luck.

This sounds more like a gastrointestinal problem to me. I recommend switching to a bland diet like Hills prescription i/d or sensitive stomach. Check a fecal also for parasites. GSD also get pancreatic insufficiency that can have similar symptoms and that is treated with an enzyme supplement. I recommend a second opinion with another veterinarian before consulting a neurosurgeon. In the meantime if you apply a thin film of Vaseline to the fur around the rectum and down the legs the diarrhea won’t stick to the fur and she will stay cleaner. Thanks for using Petco Pet Education Center, formerly Petcoach to help you care for Kelly.

With a normal stool sample and blood panel, the next steps are experimenting with diet - specifically a hypoallergenic prescription diet (such as Royal Canin Ultamino, which is definitely the most expensive option, but also the one that seems to work best in diagnosing food allergies. It takes eating ONLY the prescription food for about a month to see if it helps, and then if it does help you can certainly experiment with less expensive foods. If you she would having signs of food allergy you'd need to do a full 3 months, but for intestinal issues, you should see a response in just a couple weeks) OR a high fiber/easily digestible diet (such as Hills Fiber Response EN). Some dogs need continual probiotics to keep normal stool. Treating any underlying anxiety (if present) can also help. Finally, a gut biopsy, which is much more invasive and costly can be done. Since she isn't yet spayed, I would consider doing a gut biopsy when/if she is spayed because that would be minimal additional expense or trauma for her while she's already have an abdominal surgery. I hope that helps! Wishing you the best with this difficult issue - It can take a long long time to get to the bottom of things

Koda is beautiful! I recommend getting her in to see your vet for an exam and ask about specialty bloodwork from Texas A&M University's veterinary GI lab. They run tests to check for pancreatic enzyme levels, nutritional malabsorption and a range of other problems related to the gastrointestinal tract. Additionally, I have known some pets with chronic diarrhea do very well on a commercial raw diet, available from specialty pet stores like PetsMart and Petco.

There are several things I try for diarrhea that is not responding to typical treatments - sometimes I give the medications for a longer duration, sometimes I'll try a different antibiotic, and sometimes I'll try a different diet (which it sounds like your vet is attempting with the EN). Your vet might also want to retest a stool sample - sometimes with diarrhea there just isn't enough actual feces to get a positive results. Chronic diarrhea can also be caused by inflammatory bowel disease which is a more severe form of IBS and ultrasound and special blood testing can help diagnose this. Corticosteroid medications and B12 injections are often the recommended treatments for IBD.
