Why does my dog have spreading, crusty, bloody skin patches?

Thanks for using Petco Pet Education Center, formerly Petcoach! It is difficult to know without an examination. However, this is possibly due to a severe infection or even a growth is possible. I would highly recommend that you have her evaluated by a veterinarian for further assessment and treatment. Good luck and have a good night!

Thanks for using Petco Pet Education Center, formerly Petcoach! This is possibly due to allergies. It really comes down to figuring out what is causing his allergies so that they can be treated or the specific allergen avoided. There are many things that can cause allergies though in most cases they can be broken down into 3 big categories: flea, food and environmental allergies. Allergies are usually worked up in a stepwise fashion starting with flea allergies as this is the easiest and cheapest to take care of. If not on a flea preventative, then it would be a good idea to get started on one. If already on one then it would be a good idea to change to something else (there are many new products out in the market). If not improved in 1-3 months then it is time to move on and check for food allergies by switching to a novel diet (new protein and new carbohydrate). If that does not seem to be the issue then you are left out having to check for environmental allergies which require blood and/or skin tests. Allergies can be very frustrating to deal with at first but so rewarding at the end when we are able to treat them effectively!

Hi there and thank you for using pet coach to address your concern. Judging from the photis, this appears to have a raised area in the center. This could be a sebaceous cyst that ruptured and is now secondarily infected or has an open wound on it that won't heal. I would recommend having a veterinarian take a look at this and have some additional testing performed on it to determine what it could be. With more information on what this could be, the most appropriate treatment can then be started. If you are unable to get to your vet right now, I would recommend using an ointment called zymox topical ointment to apply to the area. If the ointment does not help aftwr 5-7 days or it worsens during that time, I would get kane to the vet for an exam. I hope this helps guide you in the right direction. Please let me know if you have any other questions or concerns.

The most common reason that we will see circular or semi-circular rings or crusts in a dog is a superficial bacterial skin infection. These areas typically start as a small bump which ruptures and forms a crust. That crust can spread and form a large area of hair loss with crusting around the edge. We can also see fungal infections that will have this same behavior. In order to determine what is causing the problem, your vet can so some simple skin tests and look at a sample under the microscope to make a diagnosis and determine the best treatment for Cooper. There are topical medications like wipes and shampoos that we will sometimes use or other times an oral medication is needed. Good luck! I hope that was helpful and answered your question.

Poor girl. If she is a young dog, I would be highly suspicious of demodex mites or scabies. You will have to get her seen by your vet for proper testing of her skin and then medication to help resolve not only the underlying issue, but the secondary skin infection she has. A short course of antibiotics will be needed no matter what, and that requires a prescription from your vet. I do hope that your furry friend Zoey is able to resolve her skin condition soon! Best wishes and take care.

Thanks for using Petco Pet Education Center, formerly Petcoach! If this is associated with itchiness, this may be due to skin allergies. There are medications such as Apoquel and prednisone which may help to decrease the itch.
