Dogs don’t get hemorrhoids the way humans do.
Did you breathe a sigh of relief when you found out? Don’t be the poop at the party, but there may be other issues. The goal is to be a responsible dog parent, and part of that is being proactive. Once you know about other genital problems that may be affecting your dog, you can work to prevent them.
Humans develop hemorrhoids when the veins in and around the lower rectum and anus swell, itch, or cause bleeding. They can be internal or external. Internal hemorrhoids are located under the skin around the anus. However, external hemorrhoids can develop on the lining of the lower rectum and anus.
Hemorrhoids affect more people than you might think. About 1 in 20 Americans suffers from hemorrhoids, according to the National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK).
Why can’t dogs get hemorrhoids?
Have you ever noticed your dog is shifting his weight or found a small amount of blood near his genitals? Hemorrhoids are so common in humans that dog parents often assume their pet has them.
However, there are differences in the anatomy of the human and canine gastrointestinal systems. For example, dogs that run horizontally have a lower GI system compared to our vertically running dogs. While this reduces the pressure on the blood vessels in the anus and rectum, it makes us more prone to hemorrhoid problems.
The Problem With Dogs Mistaken For Hemorrhoids
Rectal prolapse occurs when the inside of the rectum protrudes from the anus. It can appear in two ways: partial, a small portion of rectal tissue that shows when the dog strains and then returns to the rectum. If the anal tissue is visible, it may be intact even if the dog does not push and return to its natural position.
If the prolapse is not treated, the tissue may deteriorate over time and turn dark blue or black. It may eventually develop into a complete prolapse.
The most likely causes of this disease in dogs include severe diarrhea, parasitic infections, chronic constipation, rectal or anal tumors, inflammation, or straining to urinate or defecate.
If you notice anything protruding from your dog’s back, you should take it to the veterinarian. A veterinarian can evaluate for partial or total prolapse, treat and diagnose the underlying cause.
Complete rectal prolapse is a medical emergency that requires urgent veterinary attention. However, partial prolapses (tissue disappearing after feces) still require immediate veterinary intervention to ensure the condition does not deteriorate into complete prolapse.
anal sac disease
Anal glands in a dog’s anus produce an oily, smelly secretion that is stored in the anal sac. The anal sac is located between the inner and outer anal sphincters. These muscles allow the dog to retain stool in the rectum until it is defecated. The anal sacs drain through two holes on either side of the anus.
Therefore, blockage or infection of the anal sacs can lead to anal sac disease. This disease is one of the most common conditions affecting the anal region of dogs. However, they are more common in small obese dogs. Horrible smells, rapid movements, pain when pooping, and bottom licking are some of the symptoms your pet will need to watch out for.
If left untreated, the anal sac can become malignant, become infected, become impacted, or develop an abscess. Excessive gland production, muscle weakness in obese dogs, and an inability to regularly empty the anal sacs are typical causes of anal sac blockage.
If there is an infection, your veterinarian can manually extract the affected anal sac and prescribe antibiotics. If the condition persists, surgical removal may be required. However, fecal incontinence is one of the common side effects of surgery.
You know how they say prevention is better than cure. Proper exercise and a healthy diet of fiber to increase stool volume should do the trick.
Dogs affected by proctitis experience inflammation of the lining of the anus and rectum. The rectum is the last part of the large intestine in dogs before the anus, so occasionally this condition may indicate severe inflammation of the large intestine. Proctitis can affect any dog breed, but boxers seem to be more susceptible than other breeds. It usually appears in dogs before the age of two.
As with other gastrointestinal disorders, bloody stools, rectal licking, stomach pain, painful bowel movements, weight loss, fast running, and excessive exertion are all defining proctitis. However, contrary to what you may know, proctitis is not synonymous with colitis. The latter inflames the large intestine from the end of the small intestine to the rectum and is a common cause of proctitis.
Some other factors that can cause proctitis include rectal injury, chronic diarrhea, dietary allergies, ingestion of foreign objects, immune system disorders, and inflammatory diseases.
While proctoscopy, ultrasound, and X-rays are helpful in diagnosing proctitis, digital rectal examinations and laboratory tests are the main methods of detecting proctitis.
Surgery may be needed if there is a tumor or scar tissue in the large intestine. Proctitis can be treated by removing the trigger. You can reduce this occurrence with antibiotics, deworming medications, anti-inflammatories, and diet.
This is another condition that affects a dog’s anus. Perianal fistulas, also known as anal furuncles, are tunnel-like lesions in the deep tissues surrounding a dog’s anus. These lesions begin as small holes on the surface of the skin, grow wider and deeper, and eventually encircle the entire anus.
German Shepherds are at the highest risk for perianal fistulas. This can be attributed to their low, heavy tails found between the hipbones, covering the anus. However, other breeds such as retrievers and setters can also be affected.
While the cause of the disease is largely unknown, you may notice some general symptoms of a digestive tract infection, such as constipation, a foul-smelling odor, heavy bowel movements, and bloody stools.
Make an appointment with your veterinarian as soon as your dog shows these symptoms. In addition to asking you for information about the symptoms you’ve observed in your dog and when you first noticed them, your veterinarian will perform a physical exam. This physical exam includes a rectal examination, because an infection or blockage of the anal sac may lead to a perianal fistula.
Perianal fistulas can be managed rather than cured. The area under the tail and around the anus needs to be kept dry and clean, as the warmth and humidity can easily breed bacteria. Food allergies are sometimes associated with perianal fistulas; therefore, switching to a hypoallergenic diet may be beneficial. Medications, such as metronidazole antibiotics, immunosuppressant cyclosporine, and ketoconazole, can be used routinely.
A protruding organ or tissue through an abnormal opening is called a hernia. A perineal hernia is a rupture in the pelvic floor through which an organ enters the area between the anus and scrotum. It develops when the muscles supporting the rectum weaken, trapping the organ in a hernia. If the bladder or bowel is affected, a perineal hernia can be fatal and can inhibit a dog’s ability to urinate and defecate.
Perineal hernias are common in middle-aged, intact male dogs. Collie, Old English Sheepdog, Welsh Corgi, Boston Terrier, Pekingese, Kelpie and Kelpie mix, Dachshund and Dachshund mix, and Boxer are more likely than other breeds to Suffering from this rectal disease.
There are various factors that can cause this disorder. The tissue around the rectum in older male dogs can stretch, weaken and tear due to the extra pressure exerted by their often larger prostates during urination and defecation.
Since neutered dogs are less likely to develop hernias, some veterinarians believe that hormonal changes in intact male dogs increase the risk of developing a perineal hernia.
Weak pelvic muscles, prostate disease, and chronic constipation are some other factors that can cause a perineal hernia.
If your dog has swelling around the anus, you should see a veterinarian immediately. Your veterinarian will take your dog’s medical history and perform a rectal exam to differentiate a hernia from a tumor.
Blood tests and urinalysis may be required to create an accurate health status. These are to assess your dog’s resistance to the medication and to detect any coexisting disorders.
The type of treatment depends on the severity of the hernia. Castration and surgical revision are the recommended methods of management. However, nonsurgical alternatives exist.
Medical treatment is an option for mild cases, although it won’t cure a hernia or rupture. A high-fiber diet, stool softeners, and enemas work together to ease discomfort during bowel movements, and a urinary catheter helps decompress the bladder.
Keep in mind that it is possible for your dog to have his bladder or colon stuck in the hernia, as this option is only a temporary fix.
The recommended course of treatment for a perineal hernia is usually surgery. It immobilizes the pelvic diaphragm and strengthens it with a surgical mesh or muscle flap. Additionally, the bladder and colon may be sutured to the abdominal wall to help stabilize these organs and prevent recurrence.
Raw males are castrated to reduce hormone production and prostate size. In addition, the procedure reduces the risk of developing a perineal hernia later in life.

I am broadly interested in how human activities influence the ability of wildlife to persist in the modified environments that we create.
Specifically, my research investigates how the configuration and composition of landscapes influence the movement and population dynamics of forest birds. Both natural and human-derived fragmenting of habitat can influence where birds settle, how they access the resources they need to survive and reproduce, and these factors in turn affect population demographics. Most recently, I have been studying the ability of individuals to move through and utilize forested areas which have been modified through timber harvest as they seek out resources for the breeding and postfledging phases. As well I am working in collaboration with Parks Canada scientists to examine in the influence of high density moose populations on forest bird communities in Gros Morne National Park. Many of my projects are conducted in collaboration or consultation with representatives of industry and government agencies, seeking to improve the management and sustainability of natural resource extraction.
