Hair loss in dogs



Older dogs can also experience dog alopecia due to hormonal problems, such as an underactive thyroid gland or adrenal gland problems. General bad health, poor nutrition or an underlying disease can also make your dog’s coat lose its shine and possibly result in hair loss.
A visit to the vet should help to find the root of the problem and allow you to find a suitable treatment to get your dog back to their usual, gorgeous selves.
Investigating hair loss in dogs
Your vet will need to look for the cause of the alopecia before they can start treating it. Fleas are a common cause of itchiness and scratching, which can result in hair loss, so they might recommend a flea treatment.
Your vet might also take samples of hair or scrape a little sample of skin (painlessly) to test for ringworm and parasites, or take a blood sample to check for any underlying disease, such as a hormonal problem. Sometimes a skin allergy test will be performed, and occasionally a small skin sample will be taken. This is done under anaesthetic, so your dog won’t feel a thing.
If your vet can’t identify the reason why your pet is losing their hair, they may recommend that you consult a dermatologist for your dog.
Causes of hair loss in dogs
Alopecia in dogs can be a result of a number of skin conditions and can affect dogs of all ages, breeds and gender. Common causes of hair loss in dogs include:
- Mange, an occurrence caused by the mite ‘Demodex.’
- A disruption in the growth of hair follicles caused by trauma, infection, immune disease or endocrine system abnormalities.
- Hair follicle inflammation.
- Allergic reactions
- Diet and feeding
More widespread hair loss in your dog’s coat may indicate a more specific disease, so it’s always important to see your vet as soon as you suspect your dog may be losing his fur.
