Is My Indoor Schnauzer Restless Due to Flea Allergies or Something Else?


Dear VetBabble,

I have an indoor Schnauzer and I have noticed that he has become very restless lately. He keeps biting his tail, behind, and legs almost every minute. I suspect it might be due to flea allergies, but how can I be sure? What precautions should I take and how do I rule out other possible causes of his itchiness?


It is quite concerning to see our furry friends feeling uncomfortable due to persistent itching, and you are right to seek help. Restlessness and continuous biting or scratching at the tail, behind, and legs, are indeed signs of itching, and this could be caused by multiple factors, such as flea allergies, other parasites, or skin infections. To help you narrow down the possible causes and find the right treatment for your Schnauzer, let’s discuss the main issues in further detail.

Flea Allergies

Many dogs can suffer from flea allergies, which are caused by flea saliva. Even a single flea bite can lead to an allergic reaction in sensitive dogs, resulting in severe itching and discomfort. Just because your dog is primarily indoors does not mean he cannot catch fleas. Fleas can be easily brought into your home through other pets or even by hitching a ride on your clothing or shoes. Therefore, it is crucial to keep your dog on high-quality flea prevention monthly. Take a look at our article “Flea and Tick Control for Dogs” to understand the various preventive options available, and to choose the one that best suits your dog’s needs.

To help determine if the issue is fleas, check your dog for signs of flea infestation by looking for tiny black specks, also known as flea dirt. Running a flea comb through your dog’s fur can also help you find these telltale signs. Our article “Does My Dog Have Fleas?” provides detailed guidance on identifying fleas and seeking appropriate treatment in case of infestation.

Other Parasites

Although fleas are the most common cause of itching in dogs, several other parasites can be responsible for similar symptoms. Mites, for example, can lead to a condition called mange, which causes itching, hair loss, and skin inflammation. Our article “Does My Dog Have Mange?” provides comprehensive information on the different types of mange, how to recognize the signs, and methods of treatment. Therefore, it would be a good idea to consult with your veterinarian, who can perform tests to rule out mange and other parasites as the cause of your dog’s discomfort.

Skin Infections & Dog Allergies

If parasites have been ruled out, but your dog continues to experience restlessness and discomfort, it is time to consider other possibilities. Skin infections caused by bacteria or fungi can cause itching, and these might require antibiotic or antifungal treatments as prescribed by your veterinarian. Moreover, just like humans, dogs can also suffer from allergies to food, environmental factors, and other substances, causing itching and skin irritation. Visit our “Dog Allergies” article to learn about common allergens and how to manage and treat your dog’s allergies.


In summary, to determine what is causing your Schnauzer’s discomfort, it is essential to first rule out fleas and other parasites. If these are not the issue, consult with your veterinarian for an accurate diagnosis of skin infection or allergies, and follow up with appropriate treatment. Ensuring the wellbeing of your dog should always be a priority, and addressing the underlying cause of his itchiness will provide both of you with the peace of mind you deserve.
