Worms are rarely passed in faeces. Occasionally tapeworm segments which look like grains of rice may be seen or roundworm which is a long white worm can be found in faeces. Eggs are commonly found in stools but are really too small to see.
Dogs with worms can show outward symptoms such as a pot belly, diarrhoea and poor condition and coat but quite often show no signs at all.
Using a wormer for dogs is important because although we cannot necessarily see worms, or the results of a worm burden in a dog, we do now that dogs are most often born with worms. Puppies can be infected from mothers milk and all dogs can be infected from worm eggs in the environment. Humans especially children can be affected by dog worms too causing problems which can lead to blindness. We will cover this in a future article but this is one of the reasons why using a good dog wormer such as Drontal for dogs or our own Easimax dog wormer is so important.
