Signs of heartworm disease in dogs

Heartworms are parasites that are transmitted to dogs by mosquitos. If left untreated, they can cause severely debilitating symptoms or even death. Here are some signs of heartworm disease to look out for.
• Persistent cough and difficulty breathing. Heartworms can make their way to Fido’s lungs and surrounding veins, making your dog work harder to get the necessary oxygen.
• Lethargy and sleeping more than usual. Animals with heartworm disease are weakened and often have a hard time finding the energy for their regular activities.
• Decreased appetite and weight loss. As heartworms mature and make their way to the heart and lungs, your dog may lose interest in eating and lose weight as a result. This may cause their ribs and chest to protrude.
• Caval syndrome. Heartworm disease can cause blockages of blood to the heart, resulting in sudden collapse or death. The warning signs of caval syndrome are labored breathing, pale gums and either dark and bloody or coffee-colored urine.
Your pooch may not show any signs of having heartworms until the infestation is severe. Prevention is therefore of the utmost importance. Veterinarians recommend getting your dog tested for heartworms once a year and administering preventive medication once a month.
