What does ringworm look like in dogs and cats? - in detail
Ringworm, also known as dermatophytosis, is a common fungal infection that affects both dogs and cats. Despite its name, it is not caused by a worm but rather by a type of fungus called dermatophytes. The appearance of ringworm can vary depending on the stage of the infection and the species affected, but there are several key characteristics to look out for in both dogs and cats.
In dogs, ringworm often presents as circular or oval patches of hair loss, typically with a raised border. These lesions may appear red or inflamed and can be itchy, causing the dog to scratch or chew at the affected area. The skin within the lesion can appear crusty or scaly. In some cases, the infection may also affect the nails, causing them to become brittle, thickened, or discolored. Dogs with ringworm may exhibit signs of discomfort such as restlessness or changes in behavior due to the itchiness and irritation.
In cats, the appearance of ringworm can be somewhat different. Cats often develop circular or irregular patches of hair loss, which may be accompanied by scaling or crusting of the skin. These lesions can appear red or inflamed and may be itchy, leading the cat to groom excessively at the affected area. In addition to the skin, ringworm in cats can also affect the nails, causing them to become thickened or discolored. Some cats with ringworm may exhibit other symptoms such as lethargy or loss of appetite, although these are less common.
It is important to note that while dogs and cats can both be infected with ringworm, the specific fungal species involved can differ between the two. For example, Microsporum canis is a common cause of ringworm in cats but is less frequently seen in dogs. Similarly, Trichophyton mentagrophytes is often associated with ringworm in dogs but is less common in cats. This distinction is important for accurate diagnosis and treatment.
In both dogs and cats, the appearance of ringworm can be influenced by factors such as the severity of the infection, the individual animal's immune response, and any underlying health conditions. Early detection and prompt treatment are crucial to prevent the spread of the infection to other animals or humans. If you suspect that your pet has ringworm, it is essential to consult a veterinarian for proper diagnosis and appropriate treatment options.
