2. The dog shaking his head may be caused by dog scabies and dog ear itch mites.

Clinical symptoms: Sarcoidosis is a serious disease of puppies. It first occurs in the cheeks of the bridge of the nose, the roots of the ears and the armpits, and then spreads to the whole body. At first, the skin turned red, red nodules appeared, and then it became blisters. After the bubble burst, a thick yellow oily exudate flowed out, and the exudate dried to form a scaly scab. The affected part is itchy, and the sick dog often scratches the affected part with its claws, or rubs on the ground and various objects, thus causing serious hair loss.

The ear scabies mite parasitizes the external ear of dogs, causing a lot of ear fat secretion and lymph overflow, which often stimulates suppuration. With itching, dogs keep shaking their heads, scratching their ears, chirping, rubbing their ears with utensils, and even causing bleeding in the external auditory canal. Sometimes the lesion rotates to the heavier side, and the later lesion may spread to the ear and the back of the concha.

To treat canine sarcoidosis, firstly, wash the affected area with soapy water to remove dirt and scab, and then apply one of the following drugs: deltamethrin, sodium octametaphosphate and dimethyl ether.

To treat dog ear itch mite, paraffin oil should be dripped into the ear, gently massaged to dissolve and eliminate scab skin, and then locally wiped with oil containing acaricide.

Ivermectin or mirex injection can also be used.

3. If you have dander, it may be fleas.

It's mainly itchy. Dogs are characterized by scratching and not biting their coat, which causes depilation, short hair and abrasions, serious skin wear and seepage, and even suppurative wounds. Sometimes it can cause allergic reactions and form eczema. Carefully check the hair on the neck and tail root. Fleas or flea feces can be found in the early coat of hair growth direction.

Ordinary flea droppings sold in the market can be used, but fleas are soft and resistant to drugs, so it is difficult to kill them. We should stick to spraying.

Usually pay attention to the dog's health, take a bath often, handle it personally, and get more sunshine.
