You love your dog with all your heart, but dangerous parasites love dogs too, and often use them as hosts. Roundworms are one of the intestinal parasites that can infect your dog and cause serious health issues. Keep reading to find out how your dog can get roundworms, how the roundworm lifecycle works in dogs and what you can do if it happens to your dog.
The roundworm lifecycle1
A roundworm infection starts when a host like your dog ingests infective eggs in soil, or ingests animals (such as mice) that have eaten infective eggs and thus have larvae in their tissue. Unborn puppies can also be infected by their mother from larvae that cross the placenta.*
The larvae then make their way to the intestines, where they develop into adults. A single adult female roundworm can produce as many as 85,000 eggs per day.* These eggs are shed in the feces, which then contaminate the soil. The cycle repeats itself when the next dog becomes infected.
Protecting your dog against roundworms
Your veterinarian is your best source of advice regarding your dog’s health, so ask about controlling roundworms and other dangerous intestinal parasites with Trifexis® (spinosad + milbemycin oxime). It’s the once-monthly, beef-flavored tablet that kills fleas, prevents heartworm disease and treats and controls adult hookworm**, roundworm and whipworm infections. Trifexis is approved for use in dogs and puppies 8 weeks of age and older and weigh 5 pounds or greater.
