Worm infestations in pets can manifest through various symptoms. Changes in appetite, unexplained weight loss, persistent vomiting or diarrhea, lethargy, visible worms in feces or around the anus, bloated abdomen (especially in young animals), and increased itching or scooting are common signs. If you observe these indicators, consult your veterinarian for proper diagnosis and treatment. Regular preventive care, including deworming, is crucial for your pet’s well-being.
