Mites live under the skin of pets, not on the skin and hair. They are so small that they are invisible to the naked eye. Some parents think they can be removed by mechanical methods like fleas, but this is impossible, and drugs can be removed and killed. The image below was observed under a microscope and drawn manually.
Mites
Dear, let’s take a look at your baby Whether you have any of the following symptoms, if they are similar, in all likelihood, you are infected with mites:
(1) The disease of scabies mites is extremely contagious, and the pathogen is canine scabies mites. The inspection found that the worms were mainly parasitic on the outside of the ear tip. Tail base, feet. The skin around the mouth and eye circles and other areas with thin skin and thin hair, lesions also occur here, and in severe cases, it can spread to the whole body. Shows itching. Continually scratching and biting, resulting in depilation of the affected part, knots, and the edge of the ear shell. The skin at the base of the tail and feet is thickened, and thick bran-like scabs are densely covered. Mite and insect eggs can be found on the scab of the affected part. The disease is mainly infected through contact, and poor sanitary conditions such as overcrowding, darkness, and humidity will aggravate the occurrence and development of the disease, and people can also be infected by contact with sick dogs.
Infection on the forehead: redness, hair loss, scabs
Infection of the ventral side of the armpit: alopecia, erythema, papules
(2) Demodicosis is parasitic on hair follicles, and sebaceous glands by Demodex can cause. Necropsy found that parasites can be parasitized in the lymph nodes of dogs in severe cases, and parasites can be found in other tissues, even in the ear canal and toes (finger) of dogs. Systemic morphosis is often caused due to decreased immune function. The survey found that there are two sizes of worms. The average size of large parasites is 222.75 microns X 44.55 microns, and the average size of small parasites is 168.17 microns X 39.6 microns. Large parasites are more pathogenic. . At the beginning of the disease, the skin on both sides of the face of the dog was flushed and congested, followed by hair loss and formed many folds, and then spread to the forehead, back, chest, and abdomen and even the whole body. Seborrhea. A large number of parasites can be found by taking the skin or pus of the affected part. Simple Demodex infection generally does not have obvious itching, and if it is accompanied by fungal or scabies infection, the itching will be aggravated. Dogs are naturally infected with Demodex at a high rate. But the incidence rate is about 10.00%. The survey found that the disease can be transmitted through the placenta, and 80%-100% of the offspring of a bitch have demodicosis. The pups are usually born, and typical symptoms appear after 2 months. Demodex mites can also develop resistance to ivermectin preparations. Therefore, the disease has been increasing year by year in the past two years.
Demodex infestation: extensive ringworm, hair loss, papules
The picture below shows that there has been no treatment for a long time or the treatment is ineffective, resulting in severe mites combined with a fungal infection, which is horrible!
Mixed infection of mites and fungi: redness, hair loss, peeling, festering, bleeding, scabs
This picture is not meant to scare you; if the mites carried by your dog infect your family, this is the result Yes! Tinea pedis and tinea pedis are a little different. Have you encountered it? Of course, it is a good thing not to have encountered it, but it must be prevented!
Human infection by mites and fungi: tinea pedis and athlete’s foot
(3) Itch mites are the cause of ear mites, which are mainly parasitic in the ear canal of dogs, and sometimes crawl to other parts of the body to cause local damage. The main clinical manifestations are inflammation and congestion of the ear canal, a lot of reddish-brown or gray-white secretions in the ear canal, a fishy odor, flushing and erosion on the inside of the ear shell, the dog constantly scratching the ears and gills, or rubbing the ground or cage wall with the head, thumbs scattered on the body surface Covers a large blood scab and forms a depilatory area. The ear canal secretions were taken and pressed into tablets, and a large number of ear itching mites and eggs were found by microscopic examination. The examination found that most otitis media seen clinically was caused by itching mites. Ear itch mite disease is mainly transmitted by contact
(4) Fungal skin disease is characterized by severe itching, severe hair loss on a large area, red papules scattered on the body surface, oily thick scabs on the hair removal area, and the scabbed skin is exposed and flushed Or ulcerated epidermis, and in severe cases, ulcers are formed. With the prolongation of the course of the disease, pigmentation appeared in the affected part, the hair roots were easy to fall off, and the hair shafts were easily broken. Microscopic examination of the hair roots of the affected part showed that the hair roots were shriveled and resembled sorghum spikes, with a lot of Microsporum bambusae attached, and the hair shafts were tube-shaped. The hair shaft is surrounded by dense microspores. The disease is often co-infected with scabies mites and Demodex mites, causing each other to aggravate the occurrence and development of the disease. Skin diseases caused by Trichophyton are rare. Clinically, there are circular hair removal areas the size of thumb caps on the trunk, limbs, etc., so it is also known as “tinea ringworm.” Drum-like dandruff, itching, and skin lesions are not obvious. The disease is mainly caused by damp, dark, overcrowded, and low resistance. Severe scabies and demodicosis can induce fungal infections.
(5) Nutrient-deficiency skin disease This disease is mostly caused by the lack of certain vitamins and trace elements caused by improper feeding and management, digestion and absorption disorders, such as long-term feeding of high-protein and high-fat foods to dogs, Long-term feeding of egg yolk or spoiled feed can cause vitamin C, vitamin B, as well as selenium, calcium and other deficiencies. The coat of the affected dog is dry and dull, and the hair is easily broken and easy to fall off.
