If a dog scratches you can get worms?

No, it's not true. There are many myths about getting worms from dogs, but there is no scientific evidence to support any of them. Tapeworms and ringworm are two of the most common parasites that people think they can get from dogs, but neither one can be transmitted through scratches. Tapeworms are transmitted by ingesting the eggs, which are found in contaminated food or water. Ringworm is a fungal infection that is transmitted through direct contact with an infected person or animal.
