blood in feces

Has your dog been losing weight lately, exhibiting chronic vomiting, had diarrhea, or hematochezia (blood in the feces)? Alternatively, does your dog have an ulcerated, draining skin lesion that just won’t heal? Is your dog a sports breed like a Labrador retriever, or does he love the water? Do you live in an area with a warmer climate? Then your dog could be suffering from an infection called Pythiosis.
