Why does my Rottweiler have brown scabs, especially under his armpit?

It might be a bacterial skin infection, fungal infection, allergic dermatitis, etc. You could bathe him with a medicated dog shampoo and see if that helps. Otherwise, he should be examined by a veterinarian for treatment. Your veterinarian can do a skin scrape, cytology and/or culture to help diagnose and then prescribe medications to treat. He may need an antibiotic, anti-histamine, antifungal, corticosteroid, and or other medications.

Thank you for submitting your question regarding R. I recommend that he sees his veterinarian. If there is pus coming out from under the scabs, this typically indicates an infection. He will likely need to be treated with an oral antibiotic and/or a medicated shampoo. This is likely a result of his allergic skin, but can have another cause. I hope this information helps!

It is difficult to know the cause without seeing the bumps but he could just have a minor dermatitis/skin infection. The best thing would be to have a vet take a look at him to determine if he needs treatment. He might need an antibiotic to treat if he has an infection.

I can't tell you anything based on this picture but there is definitely something bothering him, possibly an infection or external parasites, i strongly recommend taking him to your vet ASAP in order to get it checked and treated.

Poor Rocko! This looks like it could have a bacterial component and likely an allergy component to it even though he isn't itchy. I would have your vet take a look at him and see if he could benefit from a few weeks, possibly even a month, of oral antibiotics. Your vet can also prescribe him a stronger allergy medicine like apoquel or a short course of steroids to see if this will help. I would continue with the medicated bathe twice a week. I would also add in some omega 3 fatty acids and vitamin E to help heal his coat from the inside out. I hope this helps and he starts to feel better soon!

Bruno needs to be "de-ticked", ie you need to take off the ticks. He also may be infected with sarcoptes mites (they make a bad smell and he would lose hair). You need to take him to a pet doctor for an exam and treatment. You can do preventive treatment against ticks and mites with a medicine called "Bravecto". Your pet doctor will likely have it in stock (if you are in a large city). Otherwise treatment against mites would be avermectin injections. Your vet may also recommend another tick preventive if Bravecto is not available.

In his armpits and on his chest this is a skin infection. I would recommend taking Thor to the veterinarian to get a course of antibiotics to heal this. I would also recommend getting a skin scraping for the hairloss on his back. This may be a skin mite like demodex. I would make sure Thor is on either Simparica, Nexguard or Bravecto. These are oral flea and tick preventions and are used off label for demodex and skin mites. These are prescription so I would discuss them with your veterinarian.
