1. Skin allergies
Dogs may be allergic to certain substances, such as food, grass, insects, etc., resulting in redness and swelling on the belly. Keep your dog's skin clean, bathe regularly, and use pet-specific toiletries. Choose high-quality pet skin care products to keep your dog’s skin hydrated and prevent dry skin. Avoid letting your dog come into contact with substances that may cause allergies, such as certain flowers, detergents, etc.
2. External parasitic infections
Parasitic infections such as fleas, lice, and mite infections can cause redness, swelling, and itching of the dog's skin. Deworm your dog regularly to prevent parasitic infections.
3. Trauma
Dogs may be traumatized while playing or exercising with other animals, resulting in red and swollen skin.
4. Endocrine disorders
Endocrine disorders may cause abnormal skin conditions in dogs, such as redness, swelling, hair loss, etc. Keep your dog’s daily schedule and exercise appropriately to improve your dog’s immunity. Pay attention to your dog’s diet, maintain balanced nutrition, and avoid endocrine disorders caused by overfeeding.
To ensure the health of your dog, it is recommended that you take your dog to the hospital for treatment. A pet doctor will diagnose the cause and provide corresponding treatment.
