There is plenty of ways to avoid raising a scab on a dog, but to be fullest, you can prevent its appearance based on the factors creating it, which are fleas, environmental issues, and the dog’s scratching habit.

  • Firstly, the dog must be clean and fragrant by bathing regularly, at least two times/week.
  • If your dog is exceptionally dynamic that he always smells, a specialized shower gel will be his best bet.
  • You can sometimes send him to the vets to have it shaved and washed.
  • Keeping the dog clean is a way of stimulating your dog from not scratching too frequently.
  • Therefore, it will minimize the possibility of scabs on the dog’s skin.

How to treat your dog’s crusty scabs?

Natural treatment


Scabs are easy to be sloughed off, but with those which of severe disease or with the too big scabs, you need to be patient not to make your dog painful.

Also, it’s essential to keep the dog not running anywhere during the curing process.

You should wait until there is a part of it flanking up, then apply the method.

At that time, its skin area becomes less irritated than before, and you’ll not have to worry that it will likely to open the injury and become susceptible to infection.

When a dog gets crusty scabs, he becomes very inconvenient and just wants to scratch its skin, especially the area of the scabs.

Therefore, the first thing you should do is to use warm water to pour and soak over the scabs.

If the skin area grows too thick fur, shave it but make sure you don’t make the scabs sloughed out.

Not only does it aim to sterilize the wound but this task also helps soothe it and the surrounding tissue.


  • Don’t scratch or pull the crusty scabs away but maximize the effectiveness of moisturizing them.
  • We recommend you should spray (Amazon Link) or use a wet cloth to cover the wound area of your dog.
  • Hence, his dry and itchy skin will be softened but not absolutely saturated with water.

Keep moisturizing

Before the scabs are removed, you need to keep moisturizing the wound area by using gauze to protect.

Also, you can use coconut oil (Amazon Link) instead if the area is too large, which is considered to bring the wet to the dog’s skin.

Use the dry and clean gauze to loosely cover the scabs because every wound needs to breathe and dry out any dampness such as blood or pus.

By the time, the cover will protect the scabs from environmental germs or the dog’s licking.

However, this manual way will take you from a few days to a few weeks to help your dog recover depending on the severity level of the disease.

Fortunately, we have another option for you – the clean and spray method.

Clean and spray method

This way is quite similar to the first one, but your time and effort spending on your dog’s crusty scabs will be shortened due to the presence of the two additional steps.

That is, after cleaning and moisturizing, you will use a spray to keep the injury moist and soft and then apply a topical ointment.

Afterward, you use coconut oil to moisturize as the final step as the first method.


After cleaning and softening the scab area, you apply an anti-itch and antibiotic spray on the wound.

You can buy it in a specialized store for pets or follow the directions of the vets.

If you can’t get a spray for dogs, you can alter a product for human, which is harmless for pets.

Today, there are several products you can consider, of which Zymox or First Aid Spray (Amazon Links) are the ones we highly recommend due to their quick and outstanding effect.

Apply topical

Wait about 5 minutes more, and then you can move to the next step.

Continue to apply a topical ointment on where you’ve just spray in step 3 so that the scabs will slough off after a few times repeating step 4.

NOTE: Coconut oil is a natural material, but to bring the maximized effect, you should keep your dog from licking the scabbed area caused by irritating skin issues.

An Elizabethan collar (Amazon Link) is the best choice in this situation.

You can combine cleaning with giving your dog medicines by mixing them in the dog’s food and water.

Follow all the supervision and directions of the doctor because not all medications are safe and effective.

  1. My dog is a 4 year old American bully. He has always had skin issues starting just months after I got him from his litter, it started around that time with a couple bumps on his head, my vet claimed it to be a food allergy and gave me one pill I assumed to be Prednisone for it to go away, it did. But within those first two years it came back, more intrusive, more and more on his back and not head. Brought him back to my vet and he said yup still a food allergy so I left very disappointed knowing I’d still have to continue searching for different brands of food and ingredients but those years, his bumps were just bumps and not all over. I then get him fixed his 2nd year alive and after that… it got worse than I ever thought it could. He went from a healthy coat of hair with a few bumps here and there to rapidly losing hair on his back, and then the bumps turned into nasty pus filled boil like bumps. But I kept hanging onto his “allergy”. Now here we are a year and half later with crusts all over his back, no hair, bumps filled with cottage cheese like boils or some with grey string like matter when it pops/comes out, even bleeding enough to cover a wash rag. I brought him to his vet again for this same issue now probably the 4th time and they had him in the kennel from 7 am – 6 pm with no answers until I called and mentioned the possibility of dog lupus, my vet said he would hope not but instead hope it’s his thyroid and then if that isn’t the case we would check for lupus as he’s at the prime age for lupus to full blown as well as I’ve read, lupus can also start showing after spay/neauter which is what happened- his life changed dramatically right after. Well his thyroid came back normal and my vet said I’m just going to send him home with a month+ of Prednisone and an antibacterial shampoo once a week and if it doesn’t go away or goes away but comes back we would check for lupus and do a biopsy. Well the steroid did help the cysts to go down in size as well as the base of his tail that became engorged after we got him fixed but by the time the month+ prednisone was gone his bumps were back and full blown. I call my vet again like they said and this time they don’t even care to treat him anymore, they suggest I spend double the money I’d already spent with them now on a dog dermatologist, I just don’t have the money right now we’re in a pandemic and I’m not making barely any money so I said I’d try to figure it out. But then his back gets even worse, he had three huge open sores on his back that had big green flies landed on in unisonwhile I was sitting outside with him, they were all on him at once, really freaking me out. So I call my vet again and explain for the time being I need either another bottle of Prednisone or he needs to follow through with the plan. And he said well I really don’t want dogs on Prednisone that long but if you’re not willing to take him to a derm out of town I’ll give you one more bottle and a different shampoo (a follicular wash out shampoo). So now his bumps have gone back down besides one that’s still side open and bleeding down his back. We give him cleanings every morning and wipe downs at night with the shampoo’s once a week. He also has a crust ring around his nose but there is no color change. Honestly after I fixed him he even gained 30 lbs and walking him every morning does nothing. I’ve done food trials his whole life, different brands and ingredients and NOTHING helped. He does lick his paws alot as well. Two people I know (one being my best friend) bought puppies from his same litter and they are perfectly healthy. Please give any insight so I know what to do and if saving hundreds of dollars I’ve already spent with one vet for the same thing is worth it (dermatologist). Thank you ps. I have tons of pictures if need be
