There are owners that ask if a Pomeranian will benefit from the top layer being completely shaved off during hot summer
months. The answer is no. It is the inner layer that is thick and dense and that is what will cause a tiny dog such as this to overheat (if outside too long in hot sun and especially exercising without water - always walk in the shade or before 10 AM or after 6 PM on hot days and bring travel water with you). But, of course you cannot remove that inner coat. The outer fur is long and wispy...Bring your Pom outside on a windy day and see how it blows in the wind...It does not impede air circulation.
Therefore, shaving down a Pom in anticipation of hot weather is not really productive. See below for trimming advice.
Proper Shaving & Trimming
If one does not wish to have a fluffy, furry dog, one should not opt for a Pomeranian. With this being said, their are only a few areas on this breed that should be shaved or clipped down....
1. The area around the anus. This is important for hygiene reasons. With long hairs in the way, owners may find that they feces easily sticks to the bottom of their Pom after a bowel movement. Therefore, for reasons of cleanliness, it is acceptable to shave the small area under the tail so that fecal matter does not attach to the fur. This can also help an owner notice and be more aware of when anal glands need attention.
2. The bottom of the paws. When looking at the bottom of each paw, there should not be any hairs growing out between the pads that extend out further than the pads of the paws. Therefore, one should carefully scissor any stray hairs from this area.
3. The inside of the ears. This is not a shave nor a clip. It is technically a pluck. Any stray, long hairs that are sticking out of the ears should be plucked out. If they are left and more grow, they can hold in moisture and become a breeding ground for bacteria, often causing ear infections.
4. Touch-ups can be done to the outer layer (top coat) only. This makes for a neat and tidy Pom. It can help give this breed the over all "round" look that is so lovely. This is a 1/4 inch or so trim to areas that need it to round out the shaping. Please do not cut into the dense, thick undercoat, as it will affect future hair growth.
Normally a Pomeranian will need his or her first real trim (either at home or with a groomer) after the adult coat has grown in. So, with young Poms that have their baby fur and have not yet had the change-over to the adult coat, trimming is often unnecessary. So the age that a Pomeranian should have the coat first trimmed will be anywhere from 10 to 18 months old.
