Follicular mites are mainly parasitic in hair follicles, and the head of the worm directly faces into the hair follicle, close to the hair shaft, and the head is inverted from the inside out. 1 ~ 3 hairs can be found in a hair follicle, which leads to the expansion of hair follicle and hair follicle mouth and the infiltration of inflammatory cells around it;
Sebaceous mites are mainly parasitic on sebaceous glands and sebaceous ducts, blocking the opening of sebaceous glands, and a large number of neutrophils can be seen around them, forming a micro-abscess.
Demodex mainly devours host cells and sebaceous gland secretions after parasitism. Due to the mechanical stimulation of worms and the chemical stimulation of excreta, parasitic parts can cause hair follicle enlargement, vasodilation, infiltration of surrounding cells, fibrous tissue proliferation, pathological changes of skin tissue and inflammatory reactions to varying degrees, thus causing erythema, papules, pustules, nodules and other damages. The longer the parasitic time of demodex is, the longer the course of disease is, and the more serious the disease is, resulting in different degrees of pathological changes in the skin tissue of the host, and the damage is obviously aggravated.
Because the dog's epidermis structure is relatively simple, a small amount of demodex can penetrate the epidermis, then invade the subcutaneous tissue and parasitize in other tissues and lymph nodes, resulting in repeated treatment of the disease.
Differentiation and simple treatment of dermatosis;
1. Fleas and lice can move on the body surface, inner thighs, armpits, under the neck and deep fur, and can be seen by the naked eye (because people's body temperature and body hair are different from dogs, they can't survive on people, so they can be caught boldly). The eggs of fleas and dog lice are white, so if you see black spots on dogs, that's their feces.
2, mites are generally under the skin, the dog's abdomen, the inner thigh root or little red dot's skin, and the skin around the lips is red and depilated. Dogs have ear mites, brown secretions in their ears, and sometimes they scratch their auricles because of itching.
3. Fungi, the local skin infected by dogs is depilated and damaged, and the skin is red one by one.
4, eczema, herpes and other purulent dermatitis. Generally, there are blisters and pustules on the skin of abdomen and inner thigh.
5. Dermatosis caused by allergy comes suddenly, with large area and red skin.
How to deal with it simply at home?
1. Disinfect purulent and inflamed skin with hydrogen peroxide, and apply anti-inflammatory ointment on the affected area, such as erythrosine ointment and sulfur ointment, but Piyanping contains hormones and should be used with caution.
2. If it is caused by fungi, apply clotrimazole, tinea and dyclonine ointment.
3, caused by mites, coated with sulfur ointment.
Apply these ointments three times a day for one week. )
4. Fleas and lice can be washed with trichlorfon, or with mirex drops on the back, or with Stemona, or buy a cat and dog flea ring (it must be placed for one day after it is opened). The pet store sells Fulaien, which has a good effect, but the price is more expensive.
Once the skin disease is found, the pet's daily utensils and bedding must be cleaned and exposed to the sun immediately, and the floor should be cleaned and disinfected if necessary.
Here are several ways to treat skin diseases with drugs, all of which are very cheap and have no side effects. I hope it will help everyone ~
First, the prescription of traditional Chinese medicine is good for treating various skin diseases (mites, tinea ...), and even babies lose too much hair in different seasons.
Dictyophora dictyophora 20g Sophora flavescens 15g Fructus Cnidii 15g
20 grams of mulberry bark, 20 grams of Stemona and 20 grams of licorice.
The above dosage is one dose, once, 2 ~ 3 times a week, and 4 weeks is 1 course of treatment.
Put all the traditional Chinese medicines together in a large pot and add water for decoction 15 minutes. After decocting in water, pour out the residue and cool it to a suitable temperature. Soak the pet in the soup for 10 minute. You don't need to rinse after soaking, just blow dry.
Second, the prescription for treating mites, rhubarb gallnut lotion, is washed and soaked. Main ingredients: Fructus Cnidii, Galla Chinensis, Fructus Kochiae, and Radix et Rhizoma Rhei. Shanghai sulfur soap has a good acaricidal effect, but it is alkaline. If your pet's fur is dry, please use it with caution. If you find it troublesome to buy Chinese medicine, buy a bottle of Jieeryin. Don't laugh. This is a traditional Chinese medicine formula, which can kill bacteria and diminish inflammation, and has a mild nature. Let the puppy take a bath and give it some points. Anyway, staying dry has the same effect, but it can work more or less)
Three: the method of killing fleas by cigarettes and the cleaning of cigarette immersion liquid. Tobacco leaves of cigarettes contain a lot of nicotine. Everyone knows that nicotine is so powerful that even horses can be poisoned, and they are not afraid to kill a few small fleas. Put 3~5 cigarettes into 50 ml of boiling water, filter the tobacco after 10 minutes, put the filtered liquid into a watering can and spray it evenly on the dog. Be careful not to spray on the dog's eyes, nose and mouth.
Fourth, orange peel can kill fleas. 250 grams of fresh citrus peel can be taken, sliced with a knife, wrapped with gauze, and squeezed out sweet and sour juice. Dilute the juice with 500 grams of boiling water, mix it evenly, cool it and spray it on cats and dogs, or soak it in citrus diluent with a towel and wrap it on cats and dogs. After an hour, fleas on cats and dogs will all die.
Five essential drugs for raising a dog:
In order to avoid the inconvenience caused by some unexpected situations at night or far away from animal hospitals, it is necessary for dog-raising families to prepare a common medicine box. However, some puppies are allergic to certain drugs and have doubts about the usage and dosage of various drugs, so be sure to consult a reliable veterinarian in advance.
1. surgical drugs
Hydrogen peroxide: If it is a common skin injury, you can use it to clean the wound first.
Yunnan Baiyao: If the puppy bleeds, apply the powder to the wound. If there is too much bleeding, let the puppy take some properly.
Anti-inflammatory powder (sulfanilamide crystal): a commonly used and effective wound anti-inflammatory drug. After being applied to the wound, it should be bandaged to prevent licking.
I suggest you go to the hospital first to confirm, take bubble medicine three days after the injection ... and clean the environment at home.
