My dog has a painful spot on his rear paw knuckle. What should I do?

Ouch! With any new growth like this, it's best to have your vet take a look in person, as it isn't really possible to determine what is causing the growth just from a photo. Your vet can take a sample of the growth as needed with a fine-needle aspirate, or biopsy, to check what cell type is present and if the spot needs further attention. Other causes can be calluses from rubbing, scabbing from a wound or infection under the skin, or other issues. Until you can get to the vet, it's best to keep the area clean and dry and prevent Ginger from licking or chewing at it with an Elizabethan (cone) collar or sock over the spot. Monitoring it for any additional changes such as size, oozing debris, pain, etc, is also a good idea as these observations can help your vet narrow down the cause and best treatment plan.

You will need to have this examined by your veterinarian as this could either be a harmless wart or it could be a beginning melanoma which may need to be removed while it is small. It is not possible to determine what exactly this is just from a photo. Please make an appointment with your vet.

It would be hard to tell what is going on with Harry without an exam, but if he is very painful it is best to have the spot looked at by a vet. Abscesses, tumors, allergic reactions and blisters can all cause swelling that may be painful. Abscesses (infections) tend to also be hot to the touch and may ooze discolored debris. Having your vet take a look is best, and they can recommend draining it or treating with medication to help get Harry feeling better.

Hello. It is very difficult to tell exactly what you are trying to show because of all the hair there. It does somewhat resemble a plantar wart, but I am afraid a hands on exam will probably necessary to truly identify what this is. You can try bandaging up the paw in essence creating a sneaker to protect the area, but do try to have this looked at in the near future in case additional treatment is necessary. Thanks for using Petco Pet Education Center, formerly Petcoach.

As this mass or spot is in an area of the body where we do see melanomas and other masses and where there is not a lot of extra skin, I suggest you have this examined ASAP by your veterinarian. This may be just a little skin infection easily treated with antibiotics, however in case it is a tumor, the smaller the mass the easier it is removed and the better and quicker it heals.

The bump you are seeing could be a mass, or it could be a skin lesion caused by bacterial, parasitic or fungal infection, dietary or environmental allergies or sensitivities, or could be a combination of the above. I recommend making an appointment to have your dog seen by your veterinarian to help determine the cause of the bump you’ve noticed and to make sure it is treated appropriately. The vet will likely want to look at a sample from the area under the microscope to determine what is causing the bump and to provide treatment. . In the meantime, if he is licking the area, I recommend putting an e-collar/cone on him to help prevent licking and reduce the risk of infection.

Without seeing a picture of it or seeing Jack in person, I cannot diagnose that this mass is unfortunately. In a dog his age, however, there is always a chance any mass is a malignant tumor. You will need to take him into the vet. The vet can perform a test called a fine needle aspirate on it. To do this, the vet sticks a small needle into the lump to get a sample of its cells, and examines the cells on a slide under a microscope. It's usually painless to the animal, and relatively quick to perform. Once the cause of the lump is diagnosed, the vet can discuss treatment options if needed. Best of luck.
