Recognising the Symptoms of Worms in Dogs

Worm infections are one of the most common and unpleasant parasites that dogs can catch, and they can also pose risks to humans and other animals like cats. Dogs are frequently exposed to worms through direct contact with other dogs, sharing food bowls, or walking in areas where other dogs regularly defecate, making infestations relatively easy to acquire.

Understanding and maintaining a regular worming regimen is crucial for your dog's health. Unlike flea treatments, worming products do not prevent new infestations; they only eliminate existing worms, larvae, and eggs. This means your dog can re-contract worms shortly after a treatment if exposed again. Therefore, ongoing vigilance and observation for signs of infection remain important.

In this article, we'll guide you through the common symptoms of worm infestations in dogs so you can spot potential trouble early and ensure your worming approach is effective. If your dog exhibits any of these signs, it's essential to consult a vet promptly.

1. Visible Worms in Stools

One of the clearest indications of a worm problem is spotting worms in your dog's faeces. While not all worm types or life stages are visible, small white or off-white segments or string-like pieces in stools can signify an infection. After recent worm treatment, dead worms may appear in stools; these are usually immobile and being expelled by your dog's body.

2. Diarrhoea

If your dog normally has a stable digestive system but starts experiencing regular or ongoing diarrhoea without any dietary changes, this could indicate a heavy worm infestation affecting nutrient absorption and digestion.

3. Vomiting Worms

Although most worms live in the intestines, severe infestations may provoke vomiting with visible worms or worm segments, signalling advanced infection requiring urgent veterinary care.

4. Worms Around the Back End

Occasionally, worms may be visible near your dog’s anus, especially when they are resting. Spotting live worms protruding from the back end usually indicates a significant infestation needing immediate treatment.

5. Scooting Behaviour

Scooting, where a dog drags its bottom along the ground, often arises from anal irritation. This may be caused by impacted anal glands or itchy worms, prompting your dog to seek relief.

6. Loss of Condition

A dull coat, lack of energy, and poor muscle tone are common but often overlooked signs. Worms can lead to malnutrition and anemia, which diminish your dog’s overall condition. If your dog appears unkempt or less lively, a worm check is warranted.

7. Unexplained Weight Loss

Weight loss despite normal or increased appetite is a classic symptom. Worms absorb nutrients from your dog’s food, causing nutritional deficiencies that lead to weight loss even if your dog is eating well.

8. Respiratory Problems

Lungworm is a particularly dangerous parasite that infects the lungs and respiratory tract. Your dog may exhibit coughing, laboured or noisy breathing, exercise intolerance, or other respiratory signs. These symptoms require immediate veterinary attention as lungworm can be life-threatening.

9. Bloated or Pot-bellied Abdomen

In some worm infections, especially in puppies, your dog’s belly may appear swollen or bloated, often resembling a 'pot-bellied' appearance. This is due to intestinal irritation and worm burden.

10. Lethargy and Weakness

High worm loads can cause your dog to become tired, weak, and less interested in exercise because of nutrient loss and potential anaemia.

11. Visible Worm Segments Around the Anus

You might notice small rice-like segments clinging around your dog’s rear, characteristic of tapeworm infections. This is a common sign and indicates the need for prompt treatment.

12. Skin Irritation or Dermatitis

Some worms have larvae that migrate through the skin causing irritation or dermatitis. This can lead to scratching, redness, or inflammation, which should also be investigated by a vet.

Early Worm Detection and Responsible Care

Recognising these symptoms early can prevent serious health problems and suffering for your dog. Regular vet checks, appropriate worming treatments, and good hygiene practices are vital components of responsible dog ownership. Avoid skipping worm treatments and seek veterinary advice if symptoms persist or worsen.

Understanding the signs enables you to act quickly and protect the health of your beloved pet. For finding reliable puppies or connecting with reputable breeders, ensure you research thoroughly, supporting ethical breeding practices.
