In dogs, what type of dermatitis can occur from hookworm infections?

Ventral dermatitis is associated with hookworm infections in dogs due to the way these parasites inflict damage on the host's skin. Hookworms feed on the host's blood and can lead to a range of dermatological issues, particularly when they penetrate the skin. This can result in localized inflammation and irritation, which is often more pronounced on the ventral (belly) side of the animal where exposure is greater.

These parasites can also trigger immune responses as they invade the skin, leading to dermatitis in affected areas. The ventral aspect is especially susceptible because hookworms typically enter the body through the skin and this area is often less protected. Consequently, the irritation and potential for secondary infections can manifest as dermatitis in these areas.

Other types of dermatitis listed, such as atopic dermatitis or flea allergy dermatitis, relate to different underlying causes and mechanisms, including environmental allergens or flea bites, rather than hookworm infections specifically. Therefore, ventral dermatitis is the most relevant condition to hookworm-related dermatitis in dogs.
