Among all of them, hair loss due to psychological causes, such as stress is the most complicated to treat. "Some of these cases have no solution and the hair does not recover," says José Luis González, a veterinarian expert in dermatology. Some pregnant bitches also lose their hair, in this case, by the action of their hormones.

On the other hand, sometimes, the dog's own action causes hair loss. It happens when it scratches and licks compulsively, as in the case of dogs with scabies, caused by a parasite (mite) that causes discomfort and itching, but also when the animal suffers from an allergy.

Among small dog breeds, it is known that some vaccines can infect the area where the injection is given, with the consequent hair loss (post-vaccine alopecia). Therefore, in some cases, certain vaccines are avoided in dogs with these symptoms.

On the other hand, there are races more likely to suffer from the loss of their hair. It is the case of bulldog and of boxer, which have a more sensitive skin than usual and can suffer, more easily, canine dermatitis and irritations.

Other alopecia are seasonal and affect the dog when there is less sunlight, that is, during autumn and winter. In these cases, in spring or summer, the problem is often corrected. In addition, it must be taken into account that the dogs change their hair twice a year: when it is cold, the hair is maintained and, when the high temperatures arrive, it changes.

In the case of scabies, a medication is applied to eradicate the parasite that originates it.

A improper feeding It can also cause the hair loss of the animal. In this case, the veterinarian will prescribe a I think appropriate to strengthen the hair canine. "With the dog it happens as with people: if it is fed with an unbalanced diet, which lacks the essential nutrients it needs, the dog will accuse it in the hair," says González.

In case the dog suffers from the so-called Alopecia areata, caused by stress, you have to locate the cause of your nervousness to be able to eliminate it. In some cases, the dog will recover the hair, but in others there will be no possibility.

The so-called lateral alopecia It is another type of hair loss in the dog. The veterinarian José Luis Torres explains that the cause of this condition is "the compulsive licking on the part of the can of a part of his body, like a leg. "This lick may be due to nerves or stress because the dog does not support loneliness. "Therefore, when their owners leave home, it is common for the stressed dog to express his anxiety with that compulsive licking," Torres adds.

The balanced feeding of the dog is essential to prevent hair loss. "The first step is to avoid it, but once it is detected, we must know the causes that cause it, in order to stop it," concludes the veterinarian.

Maybe they are in their time of molt. Twice a year, in the spring and autumn the shedding of the hair occurs, and they fall much more than in other times. When your dogs become adults, and being in a time of molting, surely that's why you see more hair than normal. You have to brush them twice a day to remove dead hair. If you think it is not for this, take them to the vet for a review.
