Hi there!

I would like to try to help you and your dog. Could you give me a bit more information please?

How old is your dog?

What breed?

When did this problem start? Did the vomiting blood start at the same time as the bloody stool?

Has your dog been on any medication?

What blood tests did your vet do?

Buster is 13, he is a cocker lab mix, it started two weeks ago and has gotten worse over the last week. The vet perscribeed Carafate and Metronidazole he did do blood work but it was neg for infection.
Expert:  Dr.Fiona replied 6 years ago.

In the last 6 months or so, has Buster had any changes in his weight?

Is he on any medication? Do you give him aspirin?

Is there any chance he could have eaten rat poison?

Did your vet check for kidney problems or for blood clotting disorders? Do you happen to know what Buster's PCV (hematocrit) was?

 

Customer: replied 6 years ago.
He has been between 40 to 41 lbs the last two years no major weight changes. He is not on any medication and does not take aspirin. he would not have any access to any rat poison. I don't have the information on the kidney PCV or the blood dotting. Buster still has some good energy burst but seems to be sleeping more and more.
Expert:  Dr.Fiona replied 6 years ago.

How often is he having bloody stool? How often is he vomiting? Does all the vomitus have blood in it? Does it look like coffee grounds, or is it bright red?

Is he eating? Drinking? When did you start the medication?

I'm sorry for all the questions but I am trying to get a handle on what is going on so I can offer the best advice possible.

The bloody stool is about every other movement the vomiting is happening daily. The vomit is a lighter color that looks more like bile with blood flakes or just a darker blood. he was eating two portion a day that is down to one every other day and he cannot hold this food down. The medication was started a week ago thursday I would feed him this wraped in a piece of bread. Buster is a house dog these movemenst are happening in the house which he has never done for the past ten years. He is drinking but much less than normal

Hi again,

Thanks for standing by!

Ok, so there are a few concerns here. At the one end, you are describing stool with blood in it and an increased sense of urgency. This is text-book for colitis - and the most common treatment is metronidazole (flagyl) which you mentioned that your dog is on. That makes me think your vet also thought this was the diagnosis. At the other end you are describing vomitus with flecks of blood in it. This makes me think that there is a stomach ulcer - for which the most common treatment is sucralfate (carafate) which you mention that your dog is on. Again, it makes me think that your vet thought the same thing!

Let me explain a bit more about each of these problems:

1. Colitis is an inflammation of the colon. With colitis, dogs tend to have more frequent bowel movements, a sense of urgency, sometimes straining, and sometimes mucus and even blood on the stools. The stools often start out a bit soft, or pudding like and become gelatinous, shiny and mucoid as it progresses.

Colitis just means that there is an inflammation of the colon, which is the last part of the intestine. The colon makes mucus to help the stool to pass along, so when it is inflamed it makes a lot of mucus, and also can have erosions that lead to bleeding.

Changes in diet are a common cause of colitis, as are stressful events (a move, changes in routine, visitors), parasites, and many other things. Often we don't ever find the cause.

Colitis is treated with metronidazole and with-holding food to allow the intestines a chance to heal.

2. A stomach ulcer can happen in dogs just like in humans. It can be as a result of medication (especially aspirin), kidney disease, helicobacter bacterial infection, stress or idiopathic (meaning that once again we don't know the cause). It is treated with sucralfate (carafate) which acts as a bandaid to stick to the areas that are ulcerated. Thus, it is very important that this medication be given on an EMPTY stomach. Give it at least 30 min before feeding.

Now, when we see BOTH bloody stool and blood tinged vomitus, I start to get much more worried than when I see either one alone. When we see both, we are suddenly talking about a problem all through the intestinal tract. When we see both, it is called HGE - hemorrhagic gastroenteritis. This is a problem that tends to occur in small breed dogs, often when they are much younger than Buster (2-4 years is most common). It comes on very suddenly, with vomiting, diarrhea and even frank blood in the stools.

Typically, the packed cell volume (PCV, hematocrit or HCT are other names for this) is 60% or higher. This is a blood test and is a measure of how very dehydrated and shocky dogs with this problem are.

Usually, HGE is treated aggressively in hospital with IV fluids, anti-nausea medication, antibiotics and gastric protectants. Dogs with this problem have difficulty absorbing the fluids that they take in by mouth (as evidenced by the diarrhea - the water is just coming out again), so we treat them by giving the fluid intravenously to allow the intestines to rest and heal.

In terms of what causes this, the short answer is we don't know. There are many theories - a virus, a bacteria, a food poisoning, a parasite, stress. The botXXXXX XXXXXne is that we really just don't know. Most dogs that have HGE never have another episode, however.

With hospitalization and treatment, most dogs do recover from HGE and have no lasting problems. It does, however, take several days of treatment and supportive care.

http://vetmedicine.about.com/cs/dogdiseasesh/a/HGEindogs.htm

Without seeing your little guy, I can't say whether treating him at home is advisable. But with what you have described, I am very concerned about Buster and would advise that he be seen by a veterinarian as soon as possible. Waiting until Monday could indeed be dangerous if he cannot absorb the fluids you are giving him by mouth. I am very worried about him!

I'm sorry that your little guy is going through this, and realize all too well how expensive this may be.
