Intestinal parasites cause significant health problems and welfare compromise in dogs, yet prevention through regular treatment is straightforward and effective.
Intestinal parasites cause welfare compromise through abdominal pain, nutrient malabsorption, anaemia, and in heavy infections, growth retardation and systemic illness. Puppies with heavy roundworm burdens may show obvious clinical signs including pot-bellied appearance, vomiting, and poor growth, while adult dogs often carry lighter burdens with less visible but still welfare-significant health impacts. Prevention is simple, effective, and inexpensive relative to the welfare and public health benefits. Responsible dog ownership includes regular parasite prevention, appropriate faecal disposal to reduce environmental contamination, and veterinary guidance on the parasite risks specific to the dog's lifestyle and regional exposure.
