Worms, such as heartworms , hookworms, roundworms, tapeworms and whipworms, are internal parasites. Fleas and ticks are examples of external parasites. Some possible symptoms of worms are diarrhea, vomiting and pieces of worms in your English Bulldog's stool. Often there are no signs of disease or illness, so prevention is extremely important in keeping your dog worm-free.
Your English Bulldog should be tested for worms at least once a year. These tests are usually done on a stool sample that you take to your vet. The vet will also be able to prescribe a medication that is given to your Bulldog either daily or once a month to prevent infection. You can also prevent infection by cleaning up stools from your yard. This will keep the soil from becoming contaminated, which will enable worms to live. Also, you should never let your English Bulldog eat rodents or raw meat or fish.
