My Dog Is Pooping Yellow Mucus
If you have noticed that your dog is experiencing bouts of diarrhea, wont stop farting, and they have grown cranky and irritated, then there is something wrong with your pooches health.
Yellow mucus in your dogs stool is likely to be a sign that the natural intestinal bacteria in their body has overgrown like grass through the cracks in a patio. This happens if your dog is unable to digest food because of an intolerance.
The bacteria in your buddys small intestine are needed to produce vitamins and protect from diseases.
The bacteria use the food around it to fuel these healthy actions, but if your dog cant digest some of the food left in the small intestine, then the bacteria will use those leftovers to keep feeding itself instead.
This condition happens a lot with dogs who have exocrine pancreatic insufficiency, and German Shepherds are the most likely dog bred to be suffering from this.
So now you know why your dog has yellow mucus in their stool, you need to know how to help them get better.
Yellow Mucus is due to food intolerance, so if you have recently changed your dogs diet, have a look at the new ingredients that they have used in comparison to your buddys old diet.
These are the ingredients that you should now try to avoid.

If your dog does not vomit the fluid after 12 hours, give frequent, small meals of boiled hamburger and rice or boiled chicken and rice, about ¼ cup or less per feeding. Do not give your dog over-the-counter or prescription medication unless you speak to your veterinarian.

A recentstudy on whether probiotics on dogs with acute hemorrhagic diarrhea syndrome was effective added that Acute hemorrhagic diarrhea syndrome is a common complaint in dogs presented to primary care veterinarians. The etiology is not fully understood, but there is strong evidence that C. perfringens and its toxins play a role in the pathogenesis and are responsible for the intestinal lesions in most dogs diagnosed with AHDS, via Plos One.
The results of this study demonstrated that the use of probiotics is important and advantageous to dogs suffering from acute hemorrhagic diarrhea. Both groups recovered quickly with a significant improvement on day 3 in the probiotic group and day 4 in placebo group compared to day of clinical presentation. Dogs receiving probiotic treatment also showed an accelerated normalization of Blautia, C. hiranonis, Faecalibacterium, and Turicibacter compared to dogs that were only treated symptomatically.
