One of the easiest ways to keep tabs on your dog's health is to pay attention to his poop. If he's pooping too much or too little, that can be a problem. The color and texture can also be keys to understanding how he's feeling. Obviously, if you see your dog having bright-yellow diarrhea, that can mean it's time to see your vet. Even if most of the poop is brown but you notice a lot of mucus in his stool, you should still see a vet to discover what could be causing it.
Yellow mucus in diarrhea
If the mucus is yellow and your dog has been having diarrhea, excessive farts, crankiness, or lethargy, it could be a sign that your dog's intestinal bacteria is overgrown. While the small intestines need bacteria to function properly, sometimes a dog will be unable to digest food for one reason or another. When this happens, the bacteria may eat the undigested food and use it as fuel. Small intestinal bacterial overgrowth is often seen in dogs with exocrine pancreatic insufficiency, according to PetHelpful. German shepherds are particularly prone to this condition.
While it might sound counterintuitive, the best way to treat this is with a probiotic that will help balance the good bacteria in the intestines.
Solid poop with yellow mucus
According to Canine Journal, yellow mucus in poop is usually a sign of food intolerance. If you've recently changed your dog's diet and notice yellow mucus in her stool, look at any new ingredients that could be in her food now that were not in her previous food. If there are many new ingredients, you could just switch back to her old food, or you might have to use a process of elimination to find out what specific ingredient is in her new food that doesn't agree with her.
Any color of mucus
According to petMD, a little mucus in stool is normal and actually healthy. That's why it's good to keep an eye on your dog's poop so you can understand what's normal for him and what isn't. Excessive mucus can be a sign of many different problems, including intestinal infections, parasites, irritable bowel syndrome, cancer, inflammatory disorders, hemorrhagic gastroenteritis, stress, Crohn's disease, colitis, fungal infection, clostridial enteroxtoxicosis, parvovirus, ingestion of foreign objects, and more.
With so many possibilities as to the cause of excess mucus, it is critical that you see your vet when you notice your dog has more mucus than usual in his poop for more than a day. Given that the condition can be as minor as stress or as serious as cancer, it is important to find out the real cause of the mucus. If you're nervous that it's something serious, just remember that if it's something minor, you'll be relieved to know it's no big deal, and if it is something major, you might be able to treat or at least prevent the condition from getting worse if you catch it early.
If you notice mucus along with blood, take your dog to the vet immediately. Otherwise, keep an eye on the stools for at least a day before making an appointment. Sometimes a dog will have excessive mucus for a bit and it's no problem. If the mucus level goes back to normal, your pup is probably fine and doesn't need to see the vet at all.
White stuff in stool
Sometimes it's hard to really tell what the discolorations in a dog's poop are for sure. What might look like white mucus or grains of rice could easily be worms. If you see some white stuff in stool your dog just made (old poops that turned white in the sun don't count), take your pooch to the vet for a fecal exam. If your dog has worms, these can easily be treated with a simple medication, and if it's something more serious, you may be able to tackle the problem before it gets worse.
