Thank you,

Now with the blood being dark that only suggests that it has come from the lower colon. This tends to suggest that we have colon has been irritated; either by a hard stool that was difficult to pass, due to bones damaging the gut, or secondary to issues like anal gland disease (though often we will also see a swelling to the side of the rectum or even a wee wound if the gland has ruptured), parasitic infection (ie whipworms) or with inflammation/infection of the colon (colitis).

In regards ***** ***** approach here, if she was allowed any bone material, then we need to monitor for any more and can add fiber (ie canned pumpkin, weetabix ) to her diet to help push any bone through. If she is straining, you can also add OTC cat hair ball treatment to help her pass it. Of course, any belly discomfort or more blood and we'd want her seen for this concern.

Otherwise, we can start supportive care for the other concerns. First you may consider worming to remove the concern of parasitic causes. Ideally, you want to use a good quality wormer that will cover against whipworms. Examples would be Panacur, Drontal ( or Milbemax ( as it will cover all the worms in question and help rule them out as the cause of this colonic bleeding. These are available over the counter at the vets, pet stores, and some pharmacies. Do make sure you have an idea of her weight before purchasing, so you make sure to get the right dose for her size.

As well, if we have an inflammatory colitis then this can sometimes be settled with a light/easily digestible diet. (Though bacterial induced colitis will often require antibiotic treatment). Examples of an easily digestible diet include cooked white rice with boiled chicken, boiled white fish, scrambled egg, or meat baby food (as long as its free from garlic or onion powder). There are also veterinary prescription diets that can be used in cases like this (ie Hill’s I/D or Royal Canin’s sensitivity). The easily digestible diet will be better tolerated and absorbed by the compromised gut. You can also add in an OTC canine probiotic (ie Fortiflora) to ensure the gut microflora are at optimum. We usually will try them on the diet for a week until signs settle, and then slowly weaned back to their normal diet over a week.

If you try the above and this doesn't settle in the next 24-48 hours or you are seeing blood from the rectum not associated with her passing feces, then you would want to want to follow up with her vet to make sure there is no issue with any bones. The vet will be able to examine her, assess her hydration, make sure there are no bones caught, and if they too suspect bacterial colitis, then the vet can also cover Lola with broad spectrum antibiotics to treat against the most common bacterial agents of colitis to settle this for her.

Please take care,

Dr. B.
