If you are allergic to dogs, here are some suggestions:
First see a doctor to confirm whether you are actually allergic to dogs. If you do have a dog allergy, your best bet is to avoid contact with dogs. You can minimize contact time with your dog or keep your dog in a specific area. You can clean your home regularly, especially areas where pets frequent. An air purifier that uses a high-efficiency filter can also help reduce allergens in the air.
Bathing is also a good choice, which can reduce the allergens in your pet. But be careful to use cleaning products suitable for pets and avoid frequent bathing to avoid causing damage to your pet's skin. If your allergy symptoms are severe, your doctor may recommend medications such as antihistamines or corticosteroids. However, these drugs require a doctor's prescription and cannot be used by oneself.
