Allergic dermatitis by fleas is a skin irritation caused by flea bites. It can affect dogs and cats, and even humans, but let's analyze it in pets. The first sign that the animal has the disease is that it often relaxes and scratches its body. This increases skin irritation and causes even greater damage. Observe more closely and you will see inflamed, injured or patchy skin where hair has been lost.
Check the pet
Check if the pet really has fleas. Other skin conditions can also cause scratches or wounds, so brush the comb gently through the hair and look for fleas. If you can not find them, look for the "dirt" that looks like a black or red / black dandruff. Place it on a wet paper towel and if it turns reddish, it is most likely due to the pet's blood.
Bathe your pet with an anti-flea shampoo and let it act the recommended time. Use cold water to reduce itching.
Apply an ointment such as calamine lotion or other anti-itch creams to the affected area to relieve discomfort and prevent the problem from getting worse.
If the situation seems very serious and your pet has open wounds, take the animal to a veterinarian, who can prescribe antihistamines, antibiotics or steroids.
Use an effective and safe product for flea control, such as a monthly topical treatment - some brand names are Avantage, Frontline and Revolution - to kill existing fleas, as well as to reduce contact with parasites. (Check the control product to see if you can apply it immediately after the shampoo). You can use a flea collar, but they are less effective.
Prevent the pet from re-infecting
Clean the entire house to eliminate fleas and larvae. Wash the pet's bedding. Thoroughly vacuums the carpet, the floors, the furniture. Fleas can hide in small crevices. Use three naphthalene balls in the vacuum bag to help kill any fleas it picks up. Next, throw the bag in a trash bin outside the house. Because naphthalene balls are poisonous, keep them away from children and animals.
If the problem seems to cover a large area of the house, use an insecticide designed to kill fleas and larvae. Or call a professional extermination service.
If all else fails, call a professional extermination service. Your treatment will be in vain if the pet continues to be reinfected with fleas.
