There are lots of potential things that could cause your dog’s fur to fall out. such as mange and diabetes  or a poor diet. Also, skin allergies can cause fur loss.

If your dog’s fur falls out due to stress or anxiety, it’s going to be harder to treat. There isn’t always a solution, and sometimes the fur won’t grow back. The dog itself could be causing the hair loss due to compulsive scratching because of mange, allergies, general itchiness, or anything similar to it.

Climate and seasonal changes are also potential causes. If your dog is losing more hair than what they should, they might have health issues. If so, you should take your dog straight to the vet to find out what’s wrong with your dog. There’s nothing you can do to stop your dog’s fur from falling out, but with the right care, you can reduce the amount that does.

Some smaller breeds sometimes get infections around the area where they got vaccinated, and that can also lead to fur loss. Bulldogs and boxers, among other breeds, are more likely to experience irritation and dermatitis due to their sensitive skin.

How to treat your dog’s fur loss

Treatment for this problem depends entirely on the cause. If it´s due to a poor diet, then you need to provide your dog with better nutrition in order to strengthen your dog’s fur. If it’s a result of stress or anxiety, you need to treat what’s psychologically affecting them.

There’s also spot baldness, which happens when your dog compulsively licks a specific part of their body, like a paw. The compulsive licking could be related to anxiety, stress, or just loneliness.

Brushing your dog will also get rid of any loose, excess fur and redistribute the oils on their skin, which is essential for the health of their fur.

Olive and flaxseed oil are great for a dog’s diet. You should give them about 5 ml (.17 oz) for every 5kg (11 lbs) of body weight. Remember that these are healthy oils because they have omega-3 fatty acids that soothe inflamed skin, reduce dandruff, and improve its skin texture.

Water-rich foods like cucumber, plantains, and lean meat (without the bones) are a good way to keep your dog hydrated. They also have healthy nutrients that will help fur stay straight and shiny, and keep it from falling out.

Even just having your dog drink lots of water can help. So make sure they always have fresh water around. Dehydration causes dry skin, which can lead to fur loss and serious health conditions.

Dogs that are especially food-sensitive are at a higher risk for diet-related fur conditions. Try different foods with them until you find the right one. Professional guidance is essential if this is an issue.

Vitamin supplements can also be really helpful. However, they can cause problems if you give your dog too many. Only give them to your dog if your vet recommends them, and follow the dosage they tell you.
