Treat skin diseases to adhere to
We know that among dogs, Teddy's hair loss is relatively good. If it is not the shedding season, as long as it is regularly groomed, there will generally not be a lot of hair loss.
I. Endocrine disorders
This kind of hair loss problem can occur in all dogs, and its early changes are pigmentation, dandruff, sparse coat, etc., and then alopecia occurs, which is symmetrically distributed on the abdominal ribs, chest and thighs of the dog.
1. Hair loss caused by thyroid dysfunction, clinically, dogs often show lethargy, fatigue, obesity, infertility, cold tolerance; dry and rough skin, sparse coat and hyperkeratosis, etc.
2. Long-term use of corticosteroids due to excessive secretion of adrenocortical tumors and pituitary adrenocorticotropic hormone.
II. Ringworm
Ringworm is caused by cutaneous opportunistic fungi (also known as dermatophytes), which can cause damage to the epidermis, hair and claws. There are three main pathogenic dermatophytes in dogs.
1. Microsporum canis exists in dogs for a long time, and only produces mild inflammation. About 50% of canine ringworm is caused by this bacteria.
2. Microsporum gypsum is a soil-loving fungus that occasionally causes ringworm in dogs in warm climates, but the inflammatory response and infection are self-limited.
3. Microsporum chinensis is the main cause of secondary ringworm in dogs, and mice are the main carriers.
The pathogenicity of dermatophytes is mainly caused by hyphae invading the hair column, hair follicle and cuticle, causing hair loss and production of dander, which mostly occurs on the head, feet and legs.
The drug of choice for treatment is griseofulvin, the daily dose is 15 mg/kg, high-fat food is fed to promote intestinal absorption, and antibacterial preparations such as clotrimazole can be removed locally.
Environmental hygiene is important to prevent skin diseases
Three, demodicosis
Local infection of Demodex is common in the face and legs. Most dogs are chronic, and some dogs develop deep tissue purulence. The skin inflammation changes in demodicosis mainly include the following two situations:
1. The local coat is sparse or completely depilated, the skin thickens, the dandruff increases and becomes black, and the swollen hair follicles can extrude waxy sebum.
2. Destroy the hair follicles and reach deep to the dermis layer, causing skin ulceration or flesh piercing swelling secondary to bacterial infection due to itching to become pyoderma.
Treatment: Treatment of large-scale Demodex infestations is relatively cumbersome.
It takes a long time to treat skin problems, so you must be patient and don't give up halfway, otherwise the previous treatment will be in vain.
