A product called the furminater is great but expensive it helps alot we use it in our grooming shop . Hairs grow to genetically programmed lengths, whis may vary in different parts of the body. Oce they reach their maximum length, dogs' hairs rest for various periods of time. Eventually ,new hair pushes outh the old hair , a phenomenon known as sheding , or blowing coat .
shedding is seasonal , with hair growth and loss taking its cue from the hours of daylight to which it's exposed . As the days grow shorter ... fall into winter... the hair grows thick. as the days grow longer ... spring into summer hair begins to drop off. But domestication has changed this seasonal cycle to and extent . House dogs , who are expose to long hours of artificial light , tend to shed small amounts year round. Surges of hormones can also induce sheddng . Intact females usually shed twice a year coinciding with their heat cycles. Femailes in the same household ofetn cycle and shed at the same time. Some males blow coat after they breed while others stay in coat year round . Spayed females usually come into a fuller coat, and they have a tendency to shed year round although some shed seasonally as well .
Dogs with double coats like huskeys consisting of a harsh , protective outer coat and a soft insulating undercoat , shed the undercoat heavily and at times their fur can look patchy . This is normal , unless the patches have no fur at all "Hypothyroidism or other hormonal diseases can lead to excessive or altered shedding , and many hereditary diseases can cause abnormal shedding . this is information from a book called the dog bible . A cream rinse for dogs helps let it sit on for a few mins 10 if you can rinse and then let the dog dry and brush the hair with a slicker and a undercoat rake . other wise try the ferminater like i said it is amazing

let me know if you use these products and how they work in your home ...
take care
