Symptoms of worm infestation in dogs vary according to the type of worm infestation. However, there are some symptoms that are common to all types of worms that help identify if a dog has worms. According to Dogs Monthly, these include weight loss, vomiting, diarrhea, and tiredness.
According to Caesar Milan, a dog coughing may be an indication of an advanced heartworm, hookworm, or roundworm infestation. Medic Animal states that a pot-bellied appearance or bloated abdomen in dogs is a clear sign of worm infestation. Another common symptom is visible worms that appear in bowel movements or even on the coat of the dog, according to Caesar Milan, who also describes low energy in a normally active dog as another indicator. Dogs Monthly states that heartworms present with breathing problems, lethargy, weight loss, bloating, and a dull coat, while tapeworms present with weight loss, an itchy rear, anal licking, bottom scooting, and diarrhea. According to Caesar Milan, vomiting and a change in appetite are other signs to watch for when it comes to worms in a dog.
Treat dogs with a complete worming solution at least every three months, according to Medic Animal, as prevention is far better than cure. Worms are dangerous and potentially fatal, so maintaining a regular worm treatment plan is essential to the health and well-being of pets.
