1. Allergy: On the basis of excluding other causes, a preliminary diagnosis can be made based on solid rashes and itching all over the body, and drug treatment can help with the diagnosis.

Antihistamine drugs, corticosteroids, adrenal glands and chemical anti-allergic drugs (chlorpheniramine, sodium methenate, etc.) are particularly effective. If the dog is prevented from coming into contact with suspected pathogenic environmental factors, the dog's itching will be significantly improved.

2. Environmental factors: Hot and humid, damp and cold, too dry, and changeable climate can directly or indirectly affect the dog's body and cause itching. For example, dogs that are exposed to stoves in winter often suffer from dry coat, excessive dandruff, and itching. Limiting their exposure to stoves will significantly improve their condition.

For dogs raised on concrete floors, their elbows often touch the ground. Almost every dog ​​can see hair loss in this area, thickening of the skin, darkening of color, calluses and frequent itching.

Clinically, it has also been seen that the scratching of fleas can cause itching in dogs. Fleas crawling on the skin cause itching, but the main reason is the skin allergic reaction caused by the bites of fleas. This inflammation is more common on the back, under the tail, etc. of dogs. Hair loss, exudative dermatitis and pigmentation occur due to self-mutilation. Calmly wait.

Bedding materials such as straw mats and sawdust can directly irritate the dog's skin, and can also cause itching due to the pollutants, bacteria, and parasites they carry. Eliminating these pathogenic environmental factors will significantly improve your dog's itching.

3. Food factors:Clinical experience shows that the lack of essential fatty acids, vitamins, minerals and other nutrients in dogs is accompanied by varying degrees of itching. Although dog feed is nutritionally complete, it is not suitable for some dogs. Vitamins and fatty acids are beneficial for dogs with unexplained itching.

4. Nervous dysfunction: This type of sick dogs may be related to central nervous system disorders, such as pseudorabies and rabies dogs.

5. Systemic disease pruritus: Many medical diseases, such as jaundice, tumors, diabetes and uremia, are often accompanied by skin itching. Mast cell tumors and lymphocytomas are easily detected clinically due to skin plaques and itching. Internal parasites transferred to the skin can also cause itching in dogs
