She was ill a few weeks ago, same symptoms. Was taken in scanned, x-rayed and nothing found. After treatment, put on drip and fish/rice diet she was back and up.


Yesterday off her food. first stool of the day clear and normal. vomited this afternoon and then passed a watery stool with blood in it

1- Is the blood in the stool or the vomit?
2- Did she have an abdominal ultrasound (sonogram)?
Customer: replied 3 years ago.

nothing in the vomit


small watery stool this afternoon with light traces of blood


yes abdominal ultrasound

1- Are you seeing mucus (jelly like) in the stool?
2- To make sure I got this right, so after a similar episode few weeks ago she went back to normal and now it is back, correct?
Customer: replied 3 years ago.

the small stool this afternoon looked slimy


She was worse a few weeks ago, only because i didnt pick up on the signs early enough but yes she is starting to exhibit similar signs.


Also panting a lot

Has she been dewormed? If so, what was used?

bob martin

1- Bob martin the spot on dewormer? Do you have the container with you to tell me what is the active ingredient?
2- Was she dewormed after the symptoms started?
Customer: replied 3 years ago.

sorry don't have the container


the deworming was quite a few weeks before the first episode, probably 8 weeks

Andrew, when we see mucus (slime) and blood in the stool it is a sign of inflammation in the lower intestinal tract (colon), the vomiting is simply a consequence of the inflammation. There are many possible causes like infections, imbalance of friendly vs unfriendly bacterias in the colon, intestinal parasites, auto immune (IBS), etc. to name a few causes. In this case, the fact that these episodes are intermittent I would place intestinal parasites high on the list, in particular a parasite called whipworm (T. vulpis). Deworming was a great idea, but, bob martin dewormer does not treat against whipworms. This is what you can do:

1- I would deworm her with Fenbendazole (panacur) give it once a day for 3 days at label dose. Then, repeat after 3 weeks.

2- Continue on a probiotic. But, use something like fortiflora. Dairy products (yogurt) can cause inflammation in the intestinal tract of dogs. Avoid dairy products. You can find this over the counter in any pet store or online.

3- Change her diet to rice (50%) and boiled boneless chicken or ground beef (50%) until the stool is normal. Then, wean back into a diet free of grains (corn, soy, gluten, etc.).

4- If after doing the above the diarrhea or blood continues then I would discuss with your veterinarian about doing blood work to rule out systemic causes. Or, an ultrasound guided biopsy of the gastrointestinal tract to take a closer look at what is happening in the intestinal tract.

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!
