If a dog itches to blood, then this is no longer just a symptom, but a serious problem that indicates the presence of diseases (possibly even of an infectious origin).
The danger of this symptom lies in the fact that an infection can get into open wounds, which will inevitably lead to bacterial damage. Such cases are treated much longer and more difficult, and the pet itself experiences terrible agony, since along with the itching, pain appears in the lesion.
The List of Possible Causes
It rarely happens that a dog immediately starts scratching until it bleeds, usually this process develops gradually. At first, you can notice that the animal pays special attention to a separate part of the body (most often these are ears, muzzle, anus). Then in this place you can notice loss of hair and small wounds from scratching. All this may indicate the development of the following diseases.
There are several types. But, it is that kind of disease that most often becomes the cause of the itching in dog, which forces her to comb herself until it bleeds. In terms of prevalence, flea dermatitis can be noted, which develops as a result of an allergic reaction to flea bites or saliva.
You can see how the pet began to behave restlessly, biting itself or violently scratching some part of the body. Bleeding wounds can form in these places due to claws.
The most severe reaction usually occurs after skin contact with detergents, acids or poisons. At the site of the lesion, a weeping spot forms, which itches so much that the dog may even whine while scratching. Only timely intake of antihistamines and regular treatment of lesions with antiseptic solutions will help here to exclude the ingress of a bacterial infection.
It is important to remember that food allergies are not curable and can only be controlled.
The difficulty lies in the fact that it is almost impossible to identify the component to which the animal has an allergic reaction. Therefore, in most cases the elimination method will be the only correct solution. By removing one of the products from the diet (or changing the brand of food), you can achieve long-term remission. But, it is difficult to keep track of this all the time (usually someone will feed the pet without the master’s knowledge, or he will find something on the street or pull it off the table). And everything starts all over again – again scratching until it bleeds, hair loss and redness of the skin.
It is very common in all breeds at any age. Normally, bacteria are present on the skin of every dog, but if they begin to multiply actively, then this is already considered a pathological process.
With bacterial infections, the animal may itch up to blood, red blisters and wounds appear in the places of the lesions. It is important to understand that it is useless to deal with the symptoms, unless the root cause that caused the activity of the bacteria is ruled out.
To begin with, a cytological determination of scrapings taken from the wounds is carried out. Depending on the depth and extent of the lesion, systemic antibacterial drugs can be used. If you do not eliminate the root cause (most often it is an allergy), then a relapse will not take long.
Very often it becomes the reason that the dog itches to blood and goes bald. In most cases, the process proceeds with the appearance of 2-3 small bald patches. The pet begins to comb these places with its paws (if it gets it).
You can get infected through objects with which the “lichen” animal came into contact or directly after close contact with him (usually cats). The diagnosis can be confirmed by microscopic examination of wool and scales taken from the affected areas. A Wood lamp can also be used, under which the spots will glow green.
In difficult cases, they may resort to a seeding procedure that will help determine the culture of the fungus. Timely appeal to the veterinarian and correctly selected antifungal drugs will help you quickly get rid of the misfortune. Much attention should be paid to disinfecting the places with which the pet comes into contact.
Most often, flies and mosquitoes bite dogs. After them, blisters appear on the skin, which itch terribly.
Not always, but there are times when animals comb them until they bleed. Bites of ants and gadflies are especially unpleasant. After them, a significant area of the skin may even swell. Itching after insect bites can only be eliminated with antihistamines. It is not recommended to apply any ointments or antiseptics to the skin.
Every master should understands that if his dog constantly itches to blood, then the reason can be very serious. Unfortunately, the animal is not always brought to the clinic on time. Usually a pet arrives there with huge bleeding scratches complicated by bacterial lesions. Do not allow such a development of events, bring your pets immediately after detecting alarming symptoms.
