Dry and dull coat

A dull and dry coat with visible rashes is a sign of parasitic infections, such as worms. Healthy dogs should have thick, shiny coats.

Dogs are deprived of nutrients when the worms consume their food, which can cause them to feel lethargic and lack energy. 

Worms in feces

Some dogs will have visible worms in their stool due to a severe worm infestation. Roundworms and tapeworms appear as small moving rice-like specks in a dog’s stool. It is also possible to find grain-like particles in the sleeping area or around the rear of the dog.  

Scratching or rubbing their rear

If your dog has worms in their rear, they may feel itchy and as a result, they may lick their paws, scratch the floor, or rub their paws against furniture.

3. How do dogs get worms?

Dogs can catch worms in different ways. They can nip or eat contaminated soil containing microscopic worm eggs, eat infected meat or get them through their skin, particularly their feet. Dogs can contract worms in many ways. 

From their mothers

if the mother dog is infected with roundworms or hookworms during pregnancy, this can be passed down to her pups through the placenta, which can then result in worms in the pups when they are born. When the puppies are nursing, she can pass the bacteria to them by feeding them breast milk.

As a result of ingesting infected stool or soil

When dogs ingest soil or fecal matter containing microscopic larvae or eggs of intestinal worms, these worms travel through their digestive tracts, where they continue their development into adult parasites that feed off the dog.

By ingesting contaminated meat

When dogs hunt small prey like rodents or birds, they tend to eat their kills. Dogs can become infected with parasites after consuming infected meat, especially raw meat.

External parasites

fleas and tapeworms are parasites of the intestines that are carried by external parasites. In the event that a dog eats an infected flea, the tapeworms in the flea are passed into the dog, who becomes their new host.

4. Why do worms cause diarrhea?

When a dog becomes infested with worms, these parasites travel through its bodies and settle in the intestines, especially for roundworms, hookworms, tapeworms, and whipworms. Usually, these intestinal parasites reside in the host’s intestine where they feed on the host’s food. 

There are two types of worms that live in the digestive tract: roundworms live in the intestines and feed on their victim’s blood, while whipworms live around the large and small intestines. Food that has been partially digested.

Hookworms also attach themselves to the lining of the intestinal walls where they extract nutrients to nourish themselves, and tapeworms use their hook-like mouthparts to attach themselves to the walls of the small intestines to feed on digested food. 

They cause diarrhea, bloody stools, lethargy, vomiting, etc. when they extract nutrients from digested food. Veterinarians can see these worms during microscopic examination of stool samples when these worms are present in an infected dog’s stool. 

5. What are the other causes of diarrhea?

Diarrhea in pets may be a sign that they have intestinal parasites, but this isn’t always the case. Dogs with normal bowel movements and solid stool may still have worms buried deep within them.

Anemia is a common symptom of many dog illnesses, such as bacterial or viral infections, organ dysfunction, intestinal worms, stress, food allergies, dietary indiscretions, among others. 

It is also possible to tell the underlying cause of dog diarrhea from the color and consistency of a dog’s stool. If your dog’s stool is soft or poor-quality, that can be a sign that something is not right.
