Why Is My Dogs Back Always Itchy

Itching is referred to in medicine as pruritus. It occurs frequently in a variety of skin conditions. The symptoms of flea allergy dermatitis and other allergic skin conditions include itching and scratching.

Is it common?

A common clinical symptom of many skin conditions is pruritus. It frequently comes with red, swollen skin patches and might result in the skin infection pyoderma. If the self-trauma is severe enough, the animal may experience hair loss, scabs, and raw, bleeding skin.

What causes pruritus?

One of the most typical causes of dog owners seeing a veterinarian is pruritus brought on by skin conditions. Some of the most frequent causes of pruritus in dogs include flea allergy dermatitis, seasonal allergies or atopy, food allergies, contact dermatitis (caused, for example, by detergents and fragrances), and sarcoptic mange (mites).

How can the itching be stopped?

Both owners and veterinarians may find it difficult and frustrating to treat skin conditions. Your pet may need to undergo a number of tests and treatments in order to determine the precise reason of their itching. These could include skin scrapings, skin cytology, and tests for bacterial or yeast infections, as well as tests for the presence of mites and other insects. This process could take weeks or months in some circumstances. Many times, the problem can only be managed, not completely cured, and some pets need lifelong care.

Is all pruritus that complicated?

No. The most frequent causes of inhalant allergies (such pollens and molds), flea bites, and food allergies in dogs are seasonal.

Are some dogs more prone to pruritus than others?

Any dog is susceptible to rashes or skin allergies. Skin issues run in many purebred dogs’ families. The prevalence of skin conditions is reported to be higher in Cocker Spaniels, Poodles, West Highland White Terriers, and Retrievers.

Can pruritus be cured?

It depends on what is causing your pet to scratch. Some animals will need periodic care for the rest of their lives. These are exceptional situations, and the majority of scratchy dogs benefit greatly from quite straightforward therapy.

Allergy shots or allergy desensitization injections may help dogs with seasonal allergies to pollen, mold, and/or mites. Contrary to popular belief, anti-inflammatory injections (such corticosteroids) that may be used to reduce itching should not be mistaken with allergy desensitizing injections.

What can I do to stop my dog from scratching his back?

It can be tempting to attempt an over-the-counter medication or home remedy because these symptoms and conditions manifest on the skin. However, because many of them fail to successfully treat the fundamental cause, treating your dog’s itch with an over-the-counter or at-home treatment isn’t always adequate.

The following treatments are frequently accessible, may provide some relief, but they might not be the best choice if your dog needs long-term care.

  • shampoos and oils available over the counter. The majority of topical therapies simply offer short-term comfort and don’t address the underlying cause of the issue. Since every dog’s skin is unique, using these over-the-counter products on a dog that already has skin sensitivities could backfire.
  • Antihistamines. Because they don’t treat the underlying cause, studies have shown that antihistamines frequently are ineffective at managing itch from skin allergies. Additionally, they can irritate your dog, resulting in sleepiness, panting, or shaking.
  • steroids on prescription.
  • Veterinarian-prescribed steroids may reduce allergic dog irritation, but they may also have unfavorable side effects of their own. For dogs on prescription steroids, increased urination, thirst, and weight gain are common side effects. They may also exhibit altered behavior, such as an increase in hostility.

Anytime of year, if you notice your pet scratching frequently, consult your veterinarian or look for a veterinary dermatologist.

Happiness, according to American poet Ogden Nash, is “having a scratch for every itch. Your dog’s definition of fulfillment is finding the solution to every ache.

What remedies are there for a dog’s intense itching?

The non-profit AKC, which was established in 1884, is the acknowledged authority on dog breeds, health, and training. The AKC is committed to improving dog sports and actively promotes responsible dog ownership.

Why does my dog keep rubbing his behind?

Whatever terminology is used, what we are referring to is dogs rubbing their back ends against the ground or licking and biting their anus and tail bases repeatedly. Some people will scratch their sides or become uneasy while they urinate. Owners frequently notice red, damp skin around the anus and tail base, as well as possible hair loss. There may occasionally be a fishy odor, a bulge adjacent to the anus, and the leaking of a repulsive fluid with a fishy odor.

Fleas, worms, and anal gland problems are three typical reasons of itchy bottoms, with anal glands at the top of the list being the main topic of this talk. Allergies, bacterial skin infections, and tumors are less frequent reasons.

After a thorough physical inspection, the first thing we do is look closely for signs of fleas and check the history of worming and flea treatment (which treatments have been used on all the family pets and how regularly) (live fleas and flea dirt).

Unless the infection is extensive and there are adult worms or tapeworm segments apparent in the feces or trapped in the fur around the bottom, worm problems might be difficult to spot on examination. In most cases, we simply treat the dog with a high-quality wormer at the recommended amount and repeat the procedure a few weeks later to evaluate if the issue has been resolved. We occasionally submit feces samples to a lab for parasite inspection.

The next step is to inspect the anal glands once we are confident that the flea and worm concerns have been resolved.

So what are the anal glands?

  • Anal glands are two tiny paired pockets that can be found at 4 and 8 o’clock, immediately inside the anus. The gland exits by a short, slender duct that leads to the surface not far from the inner anus edge. A particularly bad-smelling, greasy fluid with a brownish to grey color is produced by the cells lining the glands.
  • What function the anal glands serve aside from causing difficulties in dogs is a question we get asked frequently. There are two theories: one holds that the secretion is used to mark territory, and the other contends that it lubricates feces to facilitate easy passage.
  • Small dog breeds experience anal gland issues more frequently than giant dog breeds.
  • In healthy dogs, little amounts of secretion spontaneously seep out during periods of exercise and feces, keeping the glands empty. Some dogs’ anal glands secrete an unusually thick, semi-solid substance that is more likely to clog the gland because it cannot flow through the duct’s small opening to the outside (we call this impaction). The gland will frequently become infected in these circumstances, resulting in discomfort and inflammation. These clogged glands may occasionally burst, which will result in the formation of an abscess. The abscess may potentially burst, dripping a mixture of blood, pus, and anal gland discharge.
  • Treatment for gland infections involves expressing the gland, flushing it, and then injecting a topical antibiotic into the gland. Painkillers and occasionally a course of antibiotic tablets are also administered. Until we are satisfied that the infection has cleared up, we typically repeat the therapy once every two to three weeks. We can do this consciously in dogs who are quite relaxed, but many need to be sedated.
  • Anal gland abscesses are more severe and may necessitate surgery, a few weeks of antibiotic treatment, and painkillers in addition to getting the gland to drain and removing the unhealthy tissue.
  • In order to try and lower the danger of glands becoming impacted and becoming infected/abscessing, we advise dogs who produce a thick anal gland discharge to visit us every few months to have their glands expressed.
  • We might advise surgically removing the glands in canines who repeatedly experience anal gland problems.

Prevent that Itchy Bottom:

  • Use veterinarian medicines that are safe and efficient to regularly treat all home animals for fleas and worms.
  • Keep an eye out for your dog dragging its hind legs over the ground, turning to lick or bite its anal region or tail repeatedly, or displaying pain when urinating.
  • According to some beliefs, boosting the fiber in your dog’s diet may help to bulk up the stool and promote the gland’s natural emptying, but in our years of experience, we have not observed any benefits from doing so.
  • Keep your dog active and in shape. Dogs who are active, lean, and have good muscular tone are more likely to naturally release the secretions of their anal glands while going about their everyday activities.

Don’t overlook your dog’s signals of discomfort and come see us since anal sac impactions, infections, and abscesses can be a real “pain in the butt” for your dog if left untreated.

Parasitic Infestations

Dogs may exhibit tail- or bum-biting behavior due to a variety of parasite diseases. The most frequent offenders include ticks, worms, and fleas. It’s possible that your dog has multiple parasite species.

A particular kind of parasite that makes your dog scratch is called a flea. The base of your dog’s tail is one place where fleas frequently reside. Your dog can experience an allergic reaction to the flea’s saliva after it has been bitten by one. Dogs actually experience the most difficulty from this condition, known as flea bite dermatitis, which is why they nip at their tails and bums.

Consult your veterinarian for help if you suspect that your dog may be parasitized. With a short course of medicine, the majority of parasite kinds are simple to treat. For instance, the vet will give your dog a dewormer if they have tapeworms. There are several topical and oral medicines for fleas.

Finally, always ask your veterinarian for a prescription. You run the risk of recurrent infestations if you attempt to cure parasites on your own.

An Issue With Their Anal Glands

Bum biting and gnawing are frequently caused by swollen or clogged anal glands. Your dog’s anus has glands on both sides. These glands frequently become clogged or irritated, which makes your dog uncomfortable. This is an uncomfortable condition that frequently leads to infections.

A strong fishy smell is a typical indication of anal gland enlargement or obstruction. It has a very potent, distinctive smell that frequently provides a clear hint as to why your dog is chewing on their butt.

Bring your dog to the vet if you suspect that they may have impacted or infected anal glands. By expressing the glands, your veterinarian will be able to get rid of the clogged material.

This easy—but for many—gross—procedure will also be carried out by professional dog groomers. And if you want to, you can learn how to do it yourself. While some dogs can go their entire lifetimes without needing treatment, others require it on a regular basis.

An Injury

Consistent bum or tail biting may occur if your dog has damaged themselves and there is a wound or skin irritancy. Make careful to check your pet for any open wounds and visit the clinic right away for prompt care.

A “hot spot” is a condition that can result from an injury. Acute moist dermatitis is the medical term for the disease known as hot spots. When your dog gets a hot spot, it indicates that there is skin that is inflamed and infected with bacteria.

Not all hot spots are big. In actuality, they frequently start out quite little. Even worse, you can mistake a hot spot for an insect bite.

A hot area on your dog will typically enlarge and worsen over time. Hot spots will develop into potentially harmful lesions if left untreated.

Your dog may be repeatedly biting its tail or rump because of a hot place. However, if your dog frequently bites that location for any other reason, a hot spot could potentially form. Any little wound that a dog bites and chews can suddenly become a much larger hot spot.


Allergens in their environment, such as grasses and pollens, as well as man-made allergens, such as laundry soaps, can cause allergies in dogs. And as was already mentioned, if your dog has a flea allergy, this could make bites more painful.

Food allergies are fairly prevalent, and it can be challenging to identify the exact item that is off-putting to your dog. An “elimination diet” is typically used in the procedure to identify the problematic element.

The usual sign of food allergies is chewing on the tail. Make meticulous notes of everything your dog consumes in its diet if you think a food allergy might be the root of this undesirable behavior in your dog. Then, get in touch with a veterinarian for more advice.

A veterinarian may advise changing the dog’s diet to one that contains a novel protein and observing how the animal responds.

Feeding your dog better-quality food that doesn’t contain a lot of fillers like corn is one option you can try before visiting the vet. The maize fillers found in low-cost dog kibbles cause severe allergic responses in a lot of dogs.

Anxiety / Emotional Biting

Dogs occasionally start acting destructively toward themselves when they become bored, stressed, or anxious.

If you believe that this is the root of your dog’s undesirable behavior, take action to resolve the situation. For instance, if your dog is apprehensive, spend more time with them by taking them for walks, snuggling, or massaging them. Many problems for dogs have been resolved by simply giving them enough exercise.

What signs do my dog have of having mites?

Your dog may have mites if you detect any of the following signs in them:

  • hair fall (either in patches, or all over their coat)
  • Dandruff.
  • a lot of scratching
  • visible irritation, like skin that is red.
  • If you carefully examine their skin and remove the fur, you might even be able to spot mites.
