What is the most noticeable sign that a dog is suffering from parasites?

• A. Weight loss
• B. Weight gain
• C. Increased energy
• D. Shiny coat

Answer: (A)

Parasites disrupt digestion and nutrient absorption, so the most noticeable sign is weight loss as the dog isn’t getting the calories it needs. Appetite may stay the same or even increase, which is why weight gain isn’t typical. Increased energy wouldn’t usually accompany a parasitic infection, and a shiny coat points to good condition and grooming rather than a parasite problem. Other signs like diarrhea or vomiting can occur, but weight loss is the clearest clue owners tend to notice.
