Most dog owners happily brush their dog's coat or trim a few stray hairs around the paws. But there's one grooming task many people avoid because it feels awkward to talk about—keeping the hair around the rear end and private areas clean.
The truth is, a simple sanitary trim can make a huge difference to your dog's comfort and hygiene. Done correctly, it helps prevent urine and feces from sticking to the coat, reduces unpleasant odors, and keeps long-haired dogs cleaner between baths.
The good news? You don't need to remove much hair at all. A careful trim is often all it takes.

What Is a Sanitary Trim?
A sanitary trim means removing a small amount of hair around your dog's anus and genital area. Groomers commonly perform this as part of a regular grooming session, especially for breeds with continuously growing coats.
Dogs such as Poodles, Doodles, Shih Tzus, Cocker Spaniels, Maltese, and Bichons often benefit the most because long hair easily traps dirt and moisture.
If you've ever noticed your dog needing extra cleaning after going to the bathroom, this trim may solve the problem.
Why It Matters
Many owners think the trim is only for appearance. It isn't.
Keeping these areas tidy can help:
- reduce feces sticking to the coat
- prevent urine from soaking the surrounding hair
- decrease unpleasant smells
- reduce skin irritation caused by moisture
- make daily cleaning much easier
A cleaner coat is also more comfortable for your dog, especially during warm weather.

Less Is More
One of the biggest mistakes beginners make is trying to shave the area too closely.
Professional groomers don't press the clipper into the skin. Instead, they let it glide gently over the hair, removing only what is necessary.
The goal isn't a perfectly shaved area.
The goal is a clean, comfortable dog.
Keep Your Dog Calm
This part of grooming requires patience.
Lift the tail gently rather than pulling it upward, and allow your dog to stand naturally. Some dogs will try to sit down because the sensation feels strange.
If that happens, don't rush.
Pause, reassure your dog, and continue only when they're relaxed again.

Never Press the Clippers Against the Skin
The skin around your dog's rear end is extremely delicate.
Pressing clippers too firmly can cause painful irritation known as clipper burn, even if the blade isn't hot.
Instead:
- use slow, light strokes
- let the blade skim across the coat
- remove only the excess hair
- stop immediately if your dog becomes uncomfortable
Small movements are much safer than trying to finish everything in one pass.
Don't Forget the Front
Male and female dogs can also benefit from trimming a small amount of hair around the urinary area.
Again, the objective isn't shaving.
Removing just enough hair helps keep urine from soaking the coat and makes cleaning much easier after potty breaks.
Keeping your dog comfortable isn't just about sanitary grooming. Hair that grows over the eyes can also cause irritation and block your dog's vision.

When Should You Leave It to a Groomer?
Home grooming isn't the right choice for every dog.
Consider visiting a professional if your dog:
- becomes frightened by clippers
- constantly moves or tries to bite
- has matted hair around sensitive areas
- has skin irritation, wounds, or infections
- has never been clipped before
Professional groomers safely handle these situations every day.
A Small Grooming Habit That Makes a Big Difference
Sanitary trimming isn't the most glamorous part of dog ownership, but it may be one of the most practical.
A few careful minutes can help your dog stay cleaner, smell fresher, and feel more comfortable every day.
Remember, you're not trying to give your dog a perfect haircut.
You're simply making everyday life a little cleaner—and a little easier.
