Hello, my name is***** and I have over 20 years of experience as a veterinarian. I am very sorry to hear about your fellow's loose stools with a little blood.

Of course anyone would be concerned about blood in the stool. The fresher the blood appears the closer the source is to his rectum, so in his case it sounds like it is from the proximal colon (closer to the small intestine).

The important factor in all of this is how your boy feels. If he feels great then that is a good sign.

There is a condition in dogs called hemorrhagic gastroenteritis. These dogs have profuse dark, jelly-clot like, bloody diarrhea. They are very sick dogs and get dehydrated quickly so they need immediate care. Thus if he seems lethargic and/or begins vomiting an emergency veterinary visit is best.

But colitis or inflammation of the large intestine, can be due to stress, a change in diet, parasites, a viral or bacterial infection, inflammatory bowel disease or even a food allergy. Rarely a mass in the colon can be the cause, or exposure to anticoagulant rodenticides. Another possibility is an anal gland infection. These are scent glands that are located just inside the rectum and an infection can cause a bloody discharge, though should not cause loose stools.

A raw, irritated colon can take a few days to heal. Do you know if he got into anything that may have started all of this? The bleeding should clear completely with treatment over the next 2 to 3 days. If not he should be checked by his regular veterinarian and his anal glands should be checked. Well worth checking at least a couple fresh stool samples too as parasite eggs/cysts are shed intermittantly and they may be picked up on the second sample or third test if the first is negative.

If he still feels well now though we can try some things at home.

If his appetite is off and his stomach is gurgling he may have some stomach upset and reflux that can go along with his bloody stools.

To try and settle his stomach today you can try either:

1) Pepcid-ac (famotidine) at one half of a 10mg tablet per 10 to 20 pounds of body weight every 12 hours.

OR

2) Prilosec (omeprazole) at a dose of one quarter of a 10mg tablet per 10 to 20 pounds of body weight every 24 hours.

These will reduce stomach acid and should help if this is related to simple nausea and gastrointestinal irritation.

I would not feed him any food for 12 hours after the acid reducers are started. This should help stop gut spasms and restore normal gut motility. Small amounts of water or ice cubes given frequently are fine as he needs fluids after all that he has lost with bloody stools. You can give him pedialyte to replace electrolytes too but Gatorade is much too high in sugar which can make his colon irritation worse.

Today even with the fast you can start Kao-pectate at 1ml per pound or 1 tablespoon per 15 pounds of body weight every 6 to 8 hours. This is quite safe and will coat his irritated gastrointestinal tract as well as absorbing bacterial toxins. You can use it for several days until his stools look normal. You can find kao-pectate at the drug store. I like the kao-pectate formulation with kaolin and pectin better then Pepto Bismol as Pepto has salicylates which are in the same family as aspirin, and can further irritate the intestines.

If he has a tense painful abdomen, continues to have diarrhea after being on kao pectate for 24 hours, becomes very lethargic, begins vomiting or runs a fever greater than 103.5F then he really must be seen by a veterinarian as soon as possible. Make sure to take a fresh stool sample with you when you go.

After his food fast start a bland diet of 1/3 boiled, lean hamburger (or boiled, white skinless chicken), all fats and juices drained off, mixed with 2/3 boiled, plain white rice. Feed several small meals a day. You might wish to add 1-2 tablespoon of canned pumpkin to each meal as fiber helps soothe an irritated colon. I recommend adding probiotics like Fortiflora, Proviable or Benebac to his meals daily to re-establish normal gut bacteria levels too.

Once he feels better (no bloody diarrhea for 48 hours) start mixing in his regular dog food very slowly. Less bland more regular with each day. It should take a week or so to convert him back.

If your pup is vomiting and feeling poorly though it would be best that he see a veterinarian now as anything you give him orally will just come back up worsening his dehydration.

Best of luck with your pup, please let me know if you have any further questions.
