Alopecia (fur loss) in dogs
- Fortunately, alopecia in dogs is often treatable and rarely permanent.
- It can be caused by many different conditions including fleas, skin allergies and hormonal problems.
- It's important to have your dog seen by your vet if they start losing fur, especially because in some cases, it can be very irritating and painful.
Causes of alopecia
Common causes of alopecia (fur loss) in dogs include:
- Mites and lice
- Skin allergies
- Hormone disease – Hormonal problems such as hypothyroidism and Cushing's disease are a common cause of alopecia in dogs.
- Contact alopecia – Contact alopecia is when something rubs and shortens or removes the fur in an area. This is most common around the neck (if a dog wears a collar), on the elbows (if a dog lies on hard surfaces). The skin in these areas sometimes becomes dark or develop calluses, but shouldn’t be red, inflamed or crusty.
- Wounds and scars – Alopecia is common (and sometimes permanent) around infected skin, deep wounds and scars.
- Skin infections – Bacterial skin infections (such as hot spots) often cause red, itchy, bald patches.
- Over-grooming – Over grooming (grooming too much) often causes alopecia, saliva staining and red skin. It can be due to stress, pain or irritated skin.
- Seasonal alopecia – Some dogs develop harmless patches of alopecia in the autumn that don't regrow for 6-12 months. This can happen year on year. Seasonal alopecia is more common in certain breeds such as the Boxer, Bulldog Doberman and Staffordshire Bull Terrier.
- Inherited – Alopecia can be an inherited condition, meaning it's passed down from a dog's mother or father. Some breeds develop baldness e.g. hairless ears in the Staffordshire Bull Terrier and Dachshund. The Chinese Crested dog is bred to have no fur.
Other symptoms to look out for
If your dog has alopecia, it can be helpful to check for, and tell your vet about other symptoms such as:
Treatment and home remedies
The best treatment for your dog will depend on what is causing their alopecia so it’s always best to have them checked by your vet before trying any home remedies. However, once you have had a diagnosis from your vet, you may find some of the advice below useful:
- Protect any exposed skin against sun damage by avoiding the heat of the day and using pet safe sun cream.
- If your dog has contact alopecia, give them soft surfaces to lie on such as beds, blankets or mattresses. If it’s around their neck, it’s important to wash their collar regularly, check it fits them comfortably and keep the skin underneath it clean, especially during warm weather.
Consider insuring your dog as soon as you get them, before any signs of illness start. This will ensure you have all the support you need to care for them.
