As funny as it may sound, even dog poop examination and evaluation comes with rules and criteria. Dog poop is evaluated using 6 criteria. Those criteria include:

Some medications (such as Pepto Bismol) can influence the colour of the poop. If your dog recently started taking some new medications the colour alterations are most likely die to active substances in the drug. 

Although the above mentioned factors can influence the colour of the poop, the changes are usually not very dramatic.

Common abnormal dog poop colour patterns include:

• Yellow poop – usually indicates increased intestinal motility. Because of the increased passage pace, the stercobilin does not have enough time to pass its distinctive colour to the poo. This is common in digestive disorders like exocrine pancreatic insufficiency and IBD (Inflammatory Bowel Disease).
• Bright yellow poop – associated with liver problems, pancreatic problems and gall-bladder problems.
• Bright orange poop – suggestive of gall bladder and liver issues.
• Green poo – usually indicates that your god eats a lot of grass. Keep in mind that dogs tend to eat grass when troubles by gastrointestinal problems.
• Grey poop – indicates either a liver problem or disturbed nutrient absorption.
• Raspberry-jam poop – is associated with severe inflammations that lead to sloughing of the intestinal lining. The poo is not only changed in colour, but also contains small chunks of tissue. This type of stool is characteristic for hemorrhagic gastroenteritis.
• Red streaks – the presence of bright red streaks or drops are indicative of bleeding in the lower intestinal tract.
• Dark black poop – indicates the presence of digested blood. This condition is known as melena. Melena is most common in dogs with gastro-intestinal bleedings from ulcers in the upper intestinal tract.

Calling the vet: If the abnormal colour persists for more than two stools or two days in row (depending on how frequently your dog poops), it is recommended to call your veterinarian and have your dog thoroughly checked.   

Generally, the content of the poop is inspected and examined for three things:

• Foreign materials – they can only be seen if the dog ate something it cannot digest. The list of foreign materials goes as far as your imagination, or better said your dog’s imagination – grass, rocks, plastic, socks… Even certain foods can be considered foreign matters if they cannot be broken down. These foods usually include pieces of carrots (especially if not shredded) and chunks of corn.
• Blood – the presence of blood in the stool always indicates an abnormality. If your dog has diarrhea it may be accompanied with few spots of blood due to inflammation of the bowels. If your dog is constipated it also may be accompanied with few drops of blood due to straining and irritation of the bowels. If the presence of blood is consistent or in copious amount you need to bring your dog to the vet’s as soon as possible.
• Fur – dogs that tend to over-groom themselves can have big clumps of fur in their poop. It should be noted that over-grooming usually occurs secondary, as a sign of stress, boredom, allergies or certain skin issues. Another reason for excessive grooming is seasonal shedding. However, whatever the reason have your dog checked by a veterinarian. Hair clumps can be dangerous because they can cause intestinal blockage.
• Worms – you can find long, spaghetti-like strands (roundworms) or little rice-shaped tapeworm fragments.

Useful tip: When checking for worms, make sure the stool sample is fresh. If the poop has been outside for hours, chances are you will find a variety of bugs having a feast on it.

ARE CHANGES IN THE POOP’S APPEARANCE SOMETIMES NORMAL?

Yes. Under certain circumstances it is normal for the dog’s poop to look differently. If your dog’s poop is always nice-looking and then one day it looks different, do not be instantly alarmed. Pay attention to the poo and think whether something happened that could have triggered the issue.

For example, have you made a change in your dog’s diet; or has it recently been treated with de-wormers or has it been under stress and pressure. If you cannot find an obvious reason, watch your dog carefully for other signs and symptoms. If in doubt, bring a sample to your vet’s and have him examine your dog – if only to put your mind at ease.

Now that you have learned how to examine your dog’s poop and what changes to look for, it is time to discuss the right approach to keeping your dog’s poop healthy. Unfortunately there is no universal, one-approach-fits-all method for maintaining a perfectly healthy poop. Every dog is different and because of that every dog needs a tailored approach.

The factors that may influence your dog’s poop health and vary from one dog to another include:

• Eating habits – every dog has different eating habits. For example, some dogs are voracious eaters and some are picky eaters. If your dog eats too much and too quickly, the food with come out without being completely digested. That poop will contain chunks of food and smell like the food itself. In those cases it is not uncommon for the dog to eat its poop…well, why waste it?
• Diet – the type of dog poo produces depends mainly on its diet. Kibbles promote a harder stool, while moisture diets promote softer stool. Well balanced home-cooked meals are somewhere in between when it comes to the consistency of the poop they promote.
• Sensitivities and food intolerances – lately many dogs are becoming sensitive or intolerant to certain ingredients in the food. Some dogs are sensitive to lactose, some to gluten and some to added artificial additives, preservatives or colors in the food.
• Microorganism population – even though the normal microorganisms found in the gastrointestinal system of every dog are the same, their population numbers and ratios may vary between individuals. Every imbalance of the microorganisms in the gastrointestinal system results in either diarrhea or constipation.
• Presence of worms – as previously stated, worms are pesky parasites that can cause serious and even life-threatening issues in dogs.
• Systemic and metabolic diseases – unfortunately many systemic and metabolic disorders manifest with poop changes. What seems benign at first may turn out to be something dangerous.

1. Food changes

The most common reason for abnormal poop appearance is diet change. Luckily, this is easy to avoid. All you need to do is make the food switches gradually and over a prolonged period of time. Start by replacing one quarter of your dog’s old food with new one. After few days, start giving one half of the old food with one half of the new food. Then, you can give one quarter of the old food with three quarters of the new food. Within a week or two, you should be able to give your dog a full portion of the new food.

2. Diarrhea

The diarrhea is the body’s perfect mechanism for cleansing and getting rid of toxins. If it is not accompanied by other symptoms, you can deal with it on your own, by following these 4 simple steps:

• Start a fasting period for your dog – the fast should last around 6-12 hours and during this period your dog should only be offered filtered or pre-boiled water.
• Use bland diet – this is important in order to prevent recurrence of the diarrhea.
• Use probiotics – they repopulate the digestive system with healthy bacteria and boost the immune system.
• Use prebiotics – they inhibit the overgrowth of harmful bacteria and promote a healthy bacterial flora.

If the diarrhea does not improve in 24 hours take your dog at the vet’s office.

3. Constipation

The best way to deal with constipation is to keep your dog well hydrated. Adding moisture to the dog’s body usually solves constipation. To keep your dog hydrated you can add water or chicken broth to its meal. Another option is to replace its kibble with a canned version of the same feeding formula. Some human foods are also effective in resolving constipation. Those foods include green beans, sweet potatoes, pumpkins and bran flakes.

Besides hydration, another important factor that battles constipation is physical activity. Physical activity stimulates the bowels to move. A third option is to lubricate your dog’s digestive system by adding a tablespoon of olive oil, fish oil or coconut oil in your dog’s regular food.
If the constipation does not improve in 24 hours take your dog at the vet’s office.

4. Worms

 Worms are inevitable. Puppies are born with certain worms in them and throughout their entire lives they come in touch with new worms. Regular de-worming treatments are the best way to keep your dog worms-free, well…relatively worms free.

It should be noted that regularly used de-wormers are effective against the majority of worms. However, certain worms are not covered by those de-wormers. Therefore, insread of using regular broad spectrum de-wormers, we recommend to have your vet examine your vet examine your dog’s feces. Depending on what types of worms he will find, he will subscribe a proper de-wormer treatment. Another reason why it is recommended to always do a fecal analysis prior to de-worming is the dosing of the drug. For example, if the de-worming treatment is preventative, the de-wormer is used in a single dose. On the other hand if the de-worming treatment is therapeutic, the de-wormer should be administered for several days in a row. In addition, if your dog already has some worms and you only give a single, preventative dose, you are under-dosing your dog and stimulating the worms to become resistant to the de-wormer you use.

When using de-wormers it is important to keep the hygiene on a high level and remove your dog’s poop as soon as it comes out. This is important in order to prevent re-infestation.
