If you choose not to do this, it is important you know the signs and symptoms of worms in your dog; some of the symptoms such as weight loss and poor coat quality can be indicative of a wide range of health problems, and you should see your veterinarian for proper diagnosis.

  • None – worms infestations can come without any symptoms at all, in these cases, the only way to know is to have the fecal examined by your veterinarian.
  • Visible worms or eggs in feces – this is the most common way to notices if your dog has worms, however, not all worms are visible to the naked eye, so just because you don’t see them, does not mean they aren’t there.
  • Worms in dog’s fur or around dog’s rear – tapeworms are known to look like small moving segments, which dry out and resemble grains of rice.
  • Scratching rear on the ground or against furniture – this may occur because of the worms irritating the rear, but could also be because of full anal glands, as well as other medical problems. If your dog is displaying this symptom, the veterinarian should be seen.
