In the majority of cases, a bump on the withers of a dog appears after vaccination. Unfortunately, not all pet masters know this, and some veterinarians do not consider it necessary to inform them about it. But, there are also other reasons that can provoke the appearance of seals in this area. It can be the presence of parasites, trauma, the ingress of a foreign object under the skin or neoplasms, which are of a benign and malignant nature.
Description of the Main Reasons
It makes sense to wait a few days if the bump on the withers of the dog appeared after the injection. If there is no inflammatory process, then you should not worry.
If there is redness or pain during palpation, it is recommended to contact your veterinarian, as the pet may need anti-inflammatory ointments.
Particular attention should be paid to pet who have crossed the 10-year mark. During the determination of the animal and palpation of the formation, the veterinarian should exclude the following options:
It can form due to inflammation of the hair follicle, foreign body penetration under the skin, or vaccination.
A distinctive feature is a soft, predominantly red bump with a clearly visible shaft. Very often appears on the withers after injections. But, it is usually localized in the groin, limbs and muzzle.
Abscesses are always painful during puberty. Therefore, many masters do not wait for the abscess to burst on its own, but open it with their own hands or take the pet to the veterinarian for this procedure in a hospital.
The abscess must be opened, cleaned of purulent masses, treated with an antiseptic and an ointment should be applied. Access to the damaged area is limited so that the animal does not lick the wound and does not eat the medicine from the compress. Healing occurs within 3-10 days.
The chances that a bump on the withers in dog may turn out to papilloma is very high, because these formations can appear on different parts of the body.
This is especially true for smooth-haired breeds (bulldogs, staffords, pugs, etc.), which have a predisposition to the formation of warts from an early age. For example, in English Bulldogs, papillomas are most often localized on the chin, in pugs on the eyelids, in Sharpei all over the body.
There is a chance that the papilloma will transform into a malignant neoplasm, but it is so miserable that it is not considered a reason for removing the neoplasm.
The option with removal is considered only in cases where the papilloma causes discomfort to the animal (eyelid, lip, ear) or is constantly injured (limbs). Today, these growths are removed using a laser or cryodestruction.
A bump on dog’s withers may be the usual bite of a flea or other insects. In some breeds, flea saliva causes a severe allergic reaction, which manifests itself in the appearance of pea-sized red bumps all over the body.
A distinctive feature of flea dermatitis is a terrible itching, provoking the pet to scratch itself until it sores. The most correct solution would be two-time treatment for a month (every 14 days) of all animals living in the house, which are applied to the withers.
We also do not forget about mosquitoes, flies and gadflies, after the bites of which dense nodules remain on the skin. In active season, they can easily cause seals in your pet in different parts of the body.
It can also cause a hard bump on the withers of a dog at any age. In this part of the body, contact dermatitis is more common, less often food allergies. We have already mentioned flea dermatitis above.
If symptoms appear after walking in the woods or tall grass, then there is a high probability that some weed or pollen of the plant is allergenic to the animal (most often it is ragweed).
According to statistics, benign tumors are most often found in animals under the age of 10 years, then the option with malignant neoplasms is being considered.
Benign tumors, lipomas are most often found, which can reach significant sizes. They are removed without trapping healthy tissues, as they never metastasize to internal organs.
With malignant formations, the situation is much more complicated, becausr they are usually found in old animals at the stages when they are already ulcerated.

The chances that the tumor has not metastasized to regional lymph nodes and internal organs are minimal. In such cases, careful diagnosis is required, including biopsy, histology, ultrasound of the abdominal cavity, palpation and radiography of regional lymph nodes. Even in the absence of metastases, the prognosis for malignant tumors is always cautious.
Finally, I would like to remind once again that if a dog has a bump after vaccination, then this is considered acceptable. In some cases, such compaction can take several months.
