As we now know, ringworm is a fungal infection that usually takes on the appearance of a circular sore or open wound. With dogs, the fungal agents that the infection invades the hair and hair follicles. Most cases are caused by a fungal agent by the name of microsporum canis. Generally speaking, puppies and young adults are the ages when dogs will most likely develop a ringworm infection and the areas that are most susceptible are the face, ears, paws and tail. It’s rather difficult to pinpoint where a given dog would have gotten a ringworm infection but very often it comes from playing in the dirt or sand or anywhere that might have items that are unclean. Fungi often live in dark, moist locations so areas of a yard, anything in constant shade or places that don’t get cleaned very regularly are high risk. Make sure to look your dog over periodically if you notice more itching and scratching that usual so if there is an infection present, you can get a high quality ringworm treatment as soon as possible and begin the treatment process.
