Shedding

While there are exceptions to this rule, basically female Samoyeds will blow their coat twice a year and males once. Females will blow their coat usually based on their heat cycle/season. So, in the above example we are assuming this female is on a six-month cycle. How many months after the season that the female will blow coat varies. I suggest that you consult with your breeder on this to see approximately when their dogs blow coat, especially the Dam of your female Samoyed. This should give you a pretty close idea. The males usually blow coat based on when they were born (whelped). Again, this all varies from dog to dog and your best information on this will come from your breeder, observation and record keeping. When your dog starts to blow coat I would suggest that you go on a daily grooming routine of blowing the old coat out, brushing, line combing, etc. Once that is accomplished you may want to give your dog a warm, not hot, bath to get out any remaining dead coat. Follow up with another warm bath one week later approximately. Continue with the daily grooming, and weekly baths until the entire old coat is out. Otherwise, you will end up with a matted dog. This could lead to hot spots, etc. especially if the mats get damp, wet or you live in a high humidity area.
Shaving

While I do not agree with shaving a Samoyed under most circumstances that does not mean I am right or that I will never feel a need to do so. Unless it is medically necessary it is probably best not to shave your dog. Remember that the Samoyed's double/dual coat protects him or her in cold and hot weather. The Samoyed is a natural breed and natural protection is needed. If the coat is shaved too close to the body your dog could sunburn easily in the warmer months.
Once a Samoyed has been neutered (male) or spayed (female) they will usually get an abundance of coat. When this happens grooming can sometimes seem endless to the owner. Some owners will choose to clip or shave if they can not keep up with the more intense grooming. Also, the older Samoyed's skin may get more tender and sensitive making usual grooming more difficult. In these cases what may work best versus shaving your Samoyed is to invest in a good cattle dryer or other type of strong dryer. You can use the dryer to get down to the skin versus comb. This will need to be done on a regular basis so that the coat care does not become overwhelming to you. And, so that matting and hot spots will be prevented.
I will not go into much more detail on this subject as it will be a personal choice. I suggest consulting with your veterinarian, and breeder, prior to shaving your Samoyed. Also, if you must shave your Samoyed leave at least one to two inches of coat on the body to offer at least some protection from the elements
