Why Does Hair Fall Off?

There are many culprits behind doggy baldness. Before you can effectively address the problem, you’ll need to know the cause of your dog’s hair loss. You should also make a vet appointment if you believe the hair loss is caused by a medical condition.

Some serious health-related hair loss causes include:
  • The fungal infection known as ringworm
  • Mange
  • Bacterial infection
  • Cushing’s disease, which is a hormonal imbalance
  • Hypothyroidism

There are other non-medical causes of dog hair loss that you can treat at home. These include:

  • Ticks and fleas: A flea infestation can cause a severe allergic reaction, resulting in hair loss.
  • Allergies: Dogs can suffer from food and environmental allergies. If your dog is allergic to food and starts losing his hair, slowly transition him to anti-allergenic dog food.
  • Stress: Anxiety and stress can trigger hair loss in dogs. Some common causes of canine stress are loud noises, a disruption of their daily routine, new household pets or guests, and unfamiliar places.
  • Pressure sores: Also called bedsores, these small sores are localized injuries that occur in places where a dog’s body is in constant contact with a hard surface.

Divider 8The 5 Proven Methods for Hair Growth in Dogs

After you determine the cause of your pet’s hair loss, you can begin to resolve it. If it’s not caused by a serious health problem, you can easily encourage hair growth at home. Here are five quick dog hair growth methods.

1. Lemon Juice for Hair Growth

This remedy is intended as a spot treatment. The citric acid found in lemon juice has amazing antibacterial properties, meaning that it can fight bacterial infections in your dog’s skin. By getting rid of the bacteria, you can help your dog’s hair to regrow.

Add a couple of slices of lemon to 3 cups of water and let them boil and steep. Squeeze any remaining juice from the slices and strain them out. Then let the liquid cool down. Add the infusion to a spray bottle and apply it to the desired area, making sure it reaches the skin. Allow it to sit for a few minutes while you supervise your pet to ensure he doesn’t lick himself. Then thoroughly wash the lemon infusion from your pet’s hair.

2. Aloe Vera for Hair Growth

Aloe can alleviate the itching caused by fleas or food allergies. A dog’s obsessive scratching due to severe itching will lead to hair loss.

After you address the flea infestation or allergic reactions, apply a dab of aloe to your pet’s itchy areas to soothe his skin. The natural enzymes in the aloe will also remove dead skin cells, encouraging hair growth. Just make sure you use only the clear liquid at the center of the aloe vera plant. The external part of the leaf and the latex layer between the external part and the clear center can be irritating and even toxic, so please be careful to properly dispose of those parts and apply only the clear jelly.

3. Health Supplements for Hair Growth

A dog that is healthy on the inside will radiate beauty on the outside. Keep your dog healthy by feeding him a balanced diet that is rich in protein and essential vitamins and nutrients. Ask your vet if you should add supplements to your pet’s regular diet. Omega-3 supplements can relieve skin irritation and quicken the hair-growing process.

4. Apple Cider Vinegar for Hair Growth

The acetic acids in apple cider vinegar can kill fungus and bacteria while boosting your dog’s immune system. Combine equal parts vinegar with equal parts water and apply the mixture to the affected areas. You can also add a small drop of apple cider vinegar to your pet’s water.

5. Olive Oil for Hair Growth

Olive oil is commonly used in cosmetic products for a reason: it has amazing benefits for the skin! Olive oil is very nourishing, as it soothes and moisturizes the skin, encouraging new hair growth. Simply apply a little bit of olive oil and gently massage it into your dog’s skin. Do this twice a week for the best results.
