My dog's nipple is red and has pus after grooming. What should I do?

It doesn't look too serious to me. The nipple is mildly inflammed, which could be due to the surgery she had (for example it was irritated while the skin was scrubbed for the surgery). Please, monitor the nipple for the next few days. If you notice that it is getting more red, swollen or is painful for Ell, please, take her to your local vet for a check.

This looks like a mild skin infection/inflammation. I suggest you use these medicated pads on it. If after about a week to 10 days of use, the lesion is not better or looks worse then your vet should examine him.

Congratulations on your puppy! It is difficult to tell for certain from a photo, but it looks as though Mollie could have a pustule located adjacent to her nipple and that is what you are seeing. this is a little spot of infection under the skin (like a whitehead pimple in people). This isn't uncommon in puppies (we call it puppy pyoderma) and we often treat with a medicated shampoo or topical antibiotic in mild cases. I would wash the area with a mild soap and apply a triple antibiotic ointment for now and schedule an appointment with the vet to have it looked at to be on the safe side, as I said it is impossible to say for certain from a photo if this is exactly what is going on.

Hello. The nipple is definitely red & inflamed, but this does not always indicate the presence of an infection. For now, you can rub a little 1% hydrocortisone on the skin 2-3 times a day, & if it is not looking any better by early in the week, please have your veterinarian take a look. Thank you.

If this is an abnormal color change, I recommend to have her examined by the veterinarian. It could indicate an infection or developing mammary tissue. It could also be related to itchy skin. I hope this helps.

Just like in people, any unusual discharge from a nipple is not normal and could be a sign of mammary cancer. I do not think she needs to be rushed to a vet, however you should make an appointment with a vet to have it examined. It may be just mastitis, but it could be a malignant condition as well.

Hi and thanks for your request. The one with red liquid may be affected by a mastitis, which is an inflammation/infection of the mammary gland. A clinical examination at your local veterinarian is essential to confirm these clinical suspicions and treat appropriately. Antibiotics may be needed. Other care recommended for the bitch may include hydration, warm compresses using towels or cabbage leaves, and frequent expression of milk from the infected gland by hand. This alleviates discomfort and swelling while also encouraging blood flow. Hand-milking should be performed every six hours.
