This might be a silly question, but what does a sanitary trim entail? My havi is 16 months old and has been to the groomers only twice. We kept him in a long coat until we we just couldn't stand it anymore and he started to blow coat and mat. The times he went to the groomer were after he was neutered (his neck was all matted from the cone post surgery, no matter how much we combed it just coming back!!) and during the winter when it was snowing so much and he was constantly getting wet from the snow and snow stuck to his legs and "armpits" causing him to mat more despite combing. Since he was clipped very short on his body when going to the groomers after those occasions, I am wondering what it would be like if he is in a longer coat but with a sanitary trim? He has some tummy issues from time to time, meaning poop getting stuck on his rear end fur. Does a sanitary trim mean having the rear end cut very short? How does this look with the rest of the coat on the longer side? I have tried to find photos, but have had no luck. I'm sorry if this is a silly question! We have always had short coated dogs, so we are a bit new to all of the grooming lingo and possibilities!
