Yes, flea allergies can lead to a variety of other health issues in dogs. When a dog is allergic to flea saliva, even a single bite can trigger an intense allergic reaction. This can lead to excessive scratching, biting, and licking, which can result in skin infections, hot spots, and hair loss. Additionally, the stress and discomfort from the allergy can lead to anxiety and behavioral changes.

Moreover, chronic flea allergies can weaken a dog's immune system, making them more susceptible to other infections and diseases. For instance, if a dog develops a secondary bacterial or fungal infection due to scratching, it can lead to more serious health problems that may require veterinary intervention.

It's essential to manage flea infestations through regular grooming, flea prevention treatments, and maintaining a clean environment to reduce the risk of allergies and their complications. If you suspect your dog has a flea allergy, consult a veterinarian for appropriate diagnosis and treatment options.
