How Long Does It Take for Dog Hair to Grow Back?
Hair loss in dogs can be a real problem. Learn why it happens and how long it takes for dog hair to grow back.
Dogs don’t just get haircuts for aesthetic reasons or to keep them healthy. A hygienic haircut is a preventive measure against various diseases. Long hair is often piled up in tangles. Parasites such as fleas or ticks can get into them. They cause itching and make your pet scratch itself till it bleeds. Long muzzle hair causes discomfort while eating, it creeps into the eyes and this might cause visual impairment or even complete loss of vision and provoke conjunctivitis.
But how soon will your pet’s fur regrow? And are those haircuts always worth it?
How long does it take for dog hair to grow back?

Typically, new hair growth can be seen in a week or a couple of weeks after a haircut. However, the timeframes for fur regrowth can vary based on your dog breed and other factors. Sometimes, it can take from a month to a year or even several years.
The average hair growth cycle is a little over 4 months. But again, it largely depends on the breed, thickness of coat, and even your dog’s diet. You must keep in mind that your pet’s fur can’t be healthy if he doesn’t eat right.
Coat regrowth also depends on the state of your dog’s health. There are conditions that might prevent your pet’s fur from regrowing as fast as it should and/or cause dramatic hair loss.
Why is your dog losing hair?
There are many reasons why the growth of new coat may slow or stop. In the face of this problem, the hair that has already grown will go through its life cycle and fall out. As a result, a dog will noticeably go bald in a fairly short period of time.
There are multiple reasons that cause substantial loss of hair and issues with fur regrowth:
- Allergies
- Cushing’s disease (syndrome)
- Fungi, bacteria, parasites
- Pressure sores
- Acne, dermatitis, urticaria
All of these problems require medical attention. As soon as you notice the first symptoms, take your pup to the vet clinic.
