Most likely yes.
Some groomers and animal health care workers believe feeding a diet rich in fiber aids in emptying the sacs. The pressure of the firm stool against the colon wall near the anus may help to express the anal sac contents. Dogs that have an existing problem such as infection or obstructed ducts, though, probably won't respond to dietary changes; modifying the diet with more or less fiber yields inconsistent benefits. As a practitioner for over 35 years I have seldom seen a change of diet have any beneficial impact on the frequency of anal sac problems. http://www.thepetcenter.com/wai/analsacs.html
You should contact your Vet and see if the dog should be seen to make sure she does not have an infection.
A dog will commonly itch its rear end due to a full or possibly infected anal gland. (This gland is used to help dogs mark territory.) Many dogs regularly have their anal glands "expressed" (emptied) at the vet or groomer; a messy job, but it will bring your dog relief. Less likely, the irritation may be caused by an infected gland, allergies, or parasites. Make an appointment with your vet to diagnose and treat these problems.
The black stuff around a dog's anus is usually a combination of feces and anal gland secretions. This can be caused by issues such as poor diet, lack of fiber, or anal gland problems. To treat or prevent this, it is important to ensure the dog has a balanced diet with enough fiber, regular exercise, and regular vet check-ups to address any underlying health issues. Regular grooming and cleaning of the area can also help prevent buildup.
The gland must be drained by either manual pressure or surgery if it is too bad. A dog groomer can often drain them manually and a vet of course can fix the problem. I do not advise trying to do it yourself unless a professional shows you how the first time.
The human anal sac is a small gland located near the anus that secretes fluid to help with lubrication and scent marking. It functions by releasing this fluid when needed, such as during bowel movements or when a person is under stress.
If your cat has clear liquid coming from its anus, it may be a sign of a medical issue such as diarrhea or anal gland problems. It is important to take your cat to the vet for a proper diagnosis and treatment. Avoid trying to treat the issue at home without professional guidance.
There are several youtube videos that show you how to express a dog's anal glands. (Use the search words express dog's anal gland) It requires the use of those thin rubber gloves, some lubricating jelly, and paper towels. The vet who does the demonstration on one of the videos had a placid-looking lab who didn't seem to even be aware what was happening. When I tried it on my Chihuahua, he knew all right, and he didn't like it one bit. (Maybe that was because he is so small.) So from now on, I prefer to have them do it at the vet's office, even though they charge me about $15. If you go to the vet, you can ask them to show you how to do it, or advise you on how to prevent problems with the anal gland.Usually the sign that your dog's anal glands are clogged is when he starts scooting on the ground or the rug. The fluid in the gland is supposed to come out naturally when the dog poops. I found that if I make sure my dog isn't constipated, this seems to help. I mix brown rice in his food for roughage, or a little cooked vegetable (swet potato, broccoli), or a little bran or psyllium powder (not too much!).
Normally a cat does this themselves, and you won't need to do it for them unless they have something wrong with them that keeps them from being able to do it. If that is the case, you may need to do it about once a month. The cat may drag its bottom along on the floor if there is an obstruction, which would mean you would need to express the anal sacs (they aren't really glands). But normal cats don't need your help with this.

No, assimilation does not help roughage. Assimilation refers to the process by which the body absorbs and utilizes nutrients from digested food. Roughage, or dietary fiber, is not absorbed by the body but aids in digestion by promoting regular bowel movements and preventing constipation. While both processes are important for overall health, they serve different roles in digestion.
To stop your dog from scooting, you should first determine the underlying cause, which could be due to anal gland issues, parasites, or skin irritation. Consult with your veterinarian for proper diagnosis and treatment. Regularly expressing your dog's anal glands and keeping their bottom area clean can also help prevent scooting.
Roughage that is known as dietary fiber helps to prevent certain types of cancer by keeping the colon clean.
