Possible Causes of Blood in Stool

Streaks of bright red blood in your dog`s stool could be caused by an infection or injury to your dog`s sensitive rectal area, such as a ruptured anal sac. Other causes of blood in stool include: Viral and bacterial infections. Parvovirus.

Infections, Parasites, or Cancer That Affects the GI Tract

Other conditions that can affect the digestive tract, leading to bloody poop, include: Infections (bacteria or viruses such as parvovirus) Parasites (intestinal worms, coccidia, giardia) Cancer, in some cases.

Contact your vet if you see blood in your dog`s poo. They will be able to check for more serious causes, such as parvovirus or a gut blockage. It can be helpful to collect a sample of the poo show to your vet (or even a photograph if a sample isn`t possible).
If you notice a single streak of red blood in your dog`s stool, and the rest of his poop is normal, it might be a fluke. But you should still call your veterinarian. Consistent bleeding or large amounts of blood, on the other hand, indicate a more serious problem.
If your dog`s stool looks dark and jelly-like, more like strawberry jam, this could be Hemorrhagic Gastroenteritis (HGE). Your dog may be vomiting as well. HGE can be very serious and you should get to your vet right away.
Some constipated dogs may pass small amounts of liquid feces or blood due to their excessive straining. Sometimes, the liquid feces are mistaken for diarrhea, but actually, when the dog strains, a small amount of liquid fecal material is able to squeeze around the hard fecal mass.
In addition to seeing worms in your dog`s poop, intestinal worms may also cause: Mucusy or bloody diarrhea. Vomiting.
Intestinal parasites

Common intestinal parasites that can cause bloody diarrhea in dogs include: Hookworms. Whipworms. Coccidia.

When signs of parvo start showing, the stool gets more watery, becoming brownish to black diarrhea with traces of blood. After signs of parvo start to show and diarrhea gets bloody and smelly, it`s a race against time because most dog fatalities happen within 2 to 3 days after the symptoms.
Some of the signs of parvovirus include lethargy; loss of appetite; abdominal pain and bloating; fever or low body temperature (hypothermia); vomiting; and severe, often bloody, diarrhea. Persistent vomiting and diarrhea can cause rapid dehydration, and damage to the intestines and immune system can cause septic shock.
The course of treatment prescribed for your pooch will depend on the underlying cause of your pup`s bloody stool or vomit, but may include: Medications to soothe intestines. Electrolyte and fluid therapies for hemorrhagic gastroenteritis. Antibiotic therapy for certain types of infections.
When a dog`s stool contains a lot of blood and mucus (often described as looking like raspberry jam), AHDS—also known as hemorrhagic gastroenteritis—may be to blame. Treatment includes supportive care, anti-nausea drugs, fluid therapy, and antibiotics.
How do I know if my dog has worms? Coughing, diarrhea, vomiting and lethargy are the general signs the dog has worms. Other symptoms depend on the type of worm. For example, if your dog has a tapeworm, clear identifiers can be rapid weight loss or what appears to be grains of rice in their stool.
Blood in your stool can be caused by many different issues

Hemorrhoids, or swollen veins in the lower rectum, are a common cause. Other conditions that can show cause blood in the stool are: Rectal prolapse. Rectal polyps. Ulcers in the rectum.

Parvo is a potentially fatal disease. The survival rate of dogs treated by a veterinarian is 68 to 92 percent, and most puppies that survive the first three-to-four days make a complete recovery.
The scent generally associated with parvo is caused by blood in the stool. Dogs with bloody stools because of hookworms have precisely the same smell. MORE IMPORTANTLY, if a puppy is diagnosed with Parvo BEFORE there is blood in the stool, the antivirals` effectiveness is MUCH GREATER.
Dehydration is very serious; dogs with canine parvovirus refuse water and quickly dehydrate due to their constant vomiting and diarrhea symptoms.
The survival rate for hospitalization is 90%. The survival rate for at-home care is 50%.
Since parvovirus B19 infects only humans, a person cannot catch the virus from a pet dog or cat. Also, a cat or dog cannot catch parvovirus B19 from an infected person. Pet dogs and cats can get infected with other parvoviruses that do not infect humans.
Sometimes, blood in your dog`s stool is nothing to be worried about, and it`s the result of a simple problem that will get better on its own in just a few days. However, in other instances, there may be a much more severe underlying problem that needs to be addressed.

the most relevant questions and answers related to your specific issue

Q. How do I get my dog to stop chewing on things? I kennel her when I leave for a few hours, but I can’t go to the mailbox without her eating something.
ANSWER : A. If she’s young, then this is just normal puppy behavior. Don’t worry about it. The thing about puppies is, they explore using their mouths. If your puppy grabs a coat hanger, or a slipper, you should roll up a newspaper, and smack yourself on the head with it for leaving those things out.. your puppy is going to explore things, that’s normal! It is 100% up to YOU to keep those things away from your puppy when your puppy is unsupervised… even for just a moment.

Remember to never scold your puppy for grabbing these things. They are just curious little cuties, and they don’t chew things up to bother us.. Dogs do not have intentional thought, so they aren’t ever doing anything ON PURPOSE to us.. The most important thing you can do when your puppy is chewing something you don’t want her to be chewing is TRADE her the inappropriate item with a toy of hers, so she understands “no honey, that isn’t what puppies chew on… THIS is what puppies chew on!” and then begin playing with her using her toy to show her that TOYS ARE FUN.. Way more fun than a boring ol’ coat hanger.

Another helpful thing you can do is have two bags of toys. In each bag is many different kinds of toys. Lots of chew toys, lots of soft squeaky toys, lots of rope-type toys, a bunch of balls.. All kinds of things! For one week you have bag#1’s toys out for your puppy to play with.. At the end of the one week, you collect those toys, and you bring out bag#2! The toys will be more interesting/feel like new to your puppy, which will in-turn, make her chew less inappropriate things. Her toys are too fun to care about that dumb Wii-mote that you left laying around.

Hope this helps!

Q. My puppy is urinating a lot. And the lady I gave one of the puppies to said she thinks her puppy has diabetes could my puppy have it to
ANSWER : A. It is not likely that either one of these puppies has diabetes. It is very uncommon for a puppy that young to have diabetes. If your puppy is straining to urinate or is urinating very small amounts frequently and cannot seem to wait for very long between urination, he may have a urinary tract infection. It is quite possible that your puppy is completely normal. I would suggest an exam with your veterinarian and discuss the behavior with them. They may suggest a urinalysis. Your puppy should be going to the vet at 3 week intervals for vaccinations at this age, so you can discuss it when he has his next set of vaccines. The other person with the other puppy should also be taking hers to a vet for proper immunizations and she should also discuss her concerns with her vet.

Q. How long should I feed puppy food to my puppy?
ANSWER : A. A puppy should be given puppy food from around the time that the mother begins weaning her pups until the puppy reaches about the age of one year. This is generally true for all dogs, unless your veterinarian has concerns about your puppy’s growth. Under those circumstances, your veterinarian will make alternate recommendations for your puppy’s diet. Otherwise, around one year, you may begin giving your puppy an adult formula dog food at meal times.

Q. Why do l see a stream of blood in my shih tsu puppy’s feces?
ANSWER : A. It could be a number of issues centered in the large bowel, like parasites or infection. Please make an appointment with your vet and bring a stool sample.

Q. My dog doesn’t eat, what should I do?
ANSWER : A. If this is a puppy, see a veterinarian immediately. Puppies should want to eat. Common causes for anorexia in puppies include viruses (parvo is a big one), parasitism, and foreign bodies. They need immediate care – go to an emergency vet if yours isn’t open. Puppies can get low blood sugar and dehydration very quickly.

If this is an adult dog and you observe other concerning signs, such as diarrhea or decreased energy, you should see a veterinarian.

If the dog seems otherwise bright and stable, try offering different types of food: wet food, canned tripe, or cooked chicken and rice. Some dogs will go for canned baby food: chicken, turkey, or beef as the main ingredient. Make sure there are no garlic or onions in the ingredients!

Causes of anorexia in adult dogs can range from less serious to severe. Younger dogs are more likely to get into trouble- they tend to eat things they shouldn’t, and can get foreign bodies from eating things like socks, or stomach upset from getting in the trash. Any dog may stop eating due to stress, or just being a picky eater. Middle aged dogs can stop eating when they’re stressed and also have Addison’s disease, which can be fatal. Older dogs tend to stop eating when they develop cancer or renal disease.

There is no one-size-fits-all recipe to know when the right time is to take your dog to the vet. The moral of this story is, if it’s not getting better, your pup feels bad, or you’re worried – go see the vet!

Q. What solid food should I start 4 week old Pit Bull puppies on?
ANSWER : A. A puppy food designed for large breed puppies can help with rapidly growing bones and joints and can be given in a wet form easily to puppies learning to eat solids. You can also provide a dry kibble for them to try and should moisten it with water or some formula to make it easier for the puppies to eat and digest. As the puppies grow and their teeth come in, they will begin to eat and explore more of the solid food on their own.

Mom should also be on a Puppy formula while nursing her puppies as it will provide extra nutrients to both her and babies while they are in a very rapid stage of growth!

Q. My Shih Tzu had puppies 6 weeks ago. What complete dog food is reccomended to harden stools?
ANSWER : A. If your Shih Tzu is still nursing her puppies it is best to feed her a puppy or nursing formulation. This will help her to make enough milk so that the puppies can continue to grow big and strong! If she is having loose stools, adding in some pumpkin puree to her diet can safely add fiber to bulk up stools some without affecting the puppies. However, if the loose stool continues for a while, scheduling a checkup with your local vet is always best. Have fun with the puppies!

Q. What kind of food is recommended for a puppy Labrador and how often should I feed him?
ANSWER : A. Puppy food is designed specifically for the nutritional needs of young and still growing dogs, with twice the daily nutritional requirements that a mature dog needs.

Puppies are growing and developing rapidly — in their bones, muscles, joints, internal organs and immune system, to name but a few of the developmental needs that are being met by nutrition. A well balanced puppy food contains those nutrients that a puppy specifically need for this purpose, nutrients that are not necessary once the puppy has finished growing into a dog and that are not added to adult formula dog foods. For example, to build a strong body, puppy food contains about 30 percent protein, as well as the vitamins and minerals that are needed for a puppy to be healthy.
