What Does It Mean When a Dwarf Hamster Starts to Lose Fur?

Finding out what is causing your dwarf hamster to lose his fur is essential to his health and well-being. Partial or complete hair loss in hamsters can sometimes be an indication of a life-threatening disease. Additionally, the condition may be paired with unpleasant symptoms, such as itching and malnourishment. Getting to the source of the problem can help you provide your pet companion with the proper care and treatment, and improve his quality of life.

  1. Non-Disease Related Causes of Fur Loss

    • Just like humans, hamsters can lose their fur due to old age. Other causes of fur loss can include constant rubbing of his body on his feeder or on the sides of his cage. If your dwarf hamster has cage mates, they may chew on his fur or they may get into fights that can lead to fur loss. Another reason for fur loss in dwarf hamsters can be a nutritional deficiency, such as a lack of protein or B vitamins. Your veterinarian may recommend a change of environment or a dietary adjustment.

    Mites

    • Mites may be to blame for your dwarf hamster's hair loss. These skin parasites cause your hamster's skin to flake and itch. Your pet companion may constantly bite and scratch himself, resulting in scabs and sores on his skin. Because mites are contagious, your veterinarian may advice you to isolate your dwarf hamster. Additionally, he can prescribe a mite treatment and recommend that you clean your hamster's cage on a weekly basis to avoid a reinfestation.

    Ringworm

    • A ringworm infection can cause your dwarf hamster to display bald patches around his eyes, ears, nose and possibly towards his back. Your hamster may have gotten the infection from another infected hamster, from an infected person, or from contaminated bedding. Your veterinarian will examine your hamster to diagnose the condition. He may advice treatment with antifungal medication, scrubs with iodine, and mineral and vitamin supplements. Isolating your hamster and handling him with disposable gloves may also be recommended.

    Diabetes

    • Just like humans, dwarf hamsters can develop diabetes. A diabetic hamster may lose the fur on his paws and stomach. Additionally, he may drink a lot of water and urinate frequently. He may appear overly active or sleep a lot and his weight can fluctuate. Your veterinarian may recommend that you feed your hamster a diet free of sugar. Because dehydration is possible, he may also suggest that you add an oral electrolyte solution to his drinking water.

    Tumors

    • T-cell lymphoma is a type of tumor that affects your dwarf hamster's skin. His skin may be inflamed and you may notice bald patches, due to loss of fur. Tumors in hamsters must be detected early, because otherwise some of them may become malignant. Your veterinarian can examine your hamster to make a diagnosis and surgery may be required to remove the tumor.
