Why is my dog’s second poop always runny? Essential Tips

Why a dog’s stool is hard then runny

As stated in the introduction, when a dogs poop starts solid and then turns soft, it is an indication of small intestine diarrhea. Having feces of two such contrasting consistencies can be confusing for guardians. Normal dog stool should be firm, but moist and with a slight odor. Dogs with a high-fiber diet should have more voluminous stools.

Changes in consistency of the dogs stool are usually down to the absorption of water in the intestine. Poor ability to absorb water is known as malabsorption. Certain pathologies can alter the osmolarity (concentration of solute) and reduce the capacity of water absorption resulting in diarrhea. This can be contrasted with pathologies causing high water absorption, in turn causing the stool to become dry and hard. This results in constipation as it is difficult for the feces to pass.

If the dog has diarrhea, it can explain why your dog defecates more than usual. The excess water leads to fluidity of the feces, making it easier for it to pass through the intestines. Volume and consistency of the stool can also be affected. In general, diarrhea in dogs can be classified as small intestine and large intestine diarrhea.

Small bowel diarrhea is characterized by:

  • Rarely is tenesmus (difficulty) and urge to defecate seen
  • Daily frequency of defecation 2-3 times higher than normal
  • Increased volume
  • There is usually no mucus
  • There is usually no fresh blood, but can be digested blood (melena)
  • Vomiting can occur
  • Weight loss
  • In large intestine diarrhea appears:

  • Tenesmus
  • Daily frequency of defecation greater than 3 times normal rate
  • Urgency to defecate
  • Presence of mucus
  • Presence of fresh blood
  • Vomiting and weight loss are rare
