My dog has a red, raised, pus-filled lump on his leg. Is it infected?

That looks like an infection. This could be an issue by itself or ir could be related to ringworm (which humans can get) or a foreign object trapped under the skin. Zues needs to wear an elizabethan collar at all times and he needs to be examined by the veterinarian. I hope this helps.

Poor guy. You can clean this area with Betadine diluted 50:50 with warm water for now. This will help reduce some of the bacteria and help with some of the irritation/redness. I would not recommend any topical ointments on this area however. However, organic honey can be placed in small amounts on wounds like this However, if there is pus as you say, the infection is dep under the skin and requires oral antibiotics to treat effectively. Therefore, it is best to schedule an appt with your vet soon for further care/treatment. I hope that your fur baby Chicku is able to resolve this deep skin infection soon. Best wishes and take care.

It could be that Jasmen had a cyst which has now ruptured. If there is pus, however, it means there is an infection and she needs to see the vet. The vet can confirm if it is a cyst, if there is an infection, and can prescribe antibiotics. Give the vet a call in the morning to make an appointment, and gently clean the area with warm water and antiseptic soap. Keep her from licking at it, put an Ecollar on her if needed. I will put a link below on how to make one at home. Best of luck. http://dogsaholic.com/care/homemade-dog-cone.html

Thank you for submitting your question regarding Sebastian. I recommend that he sees a veterinarian as he appears to have a mass on his leg. His veterinarian will likely perform a procedure known as a fine needle aspirate to diagnose the mass. He could have a benign growth such as a histiocytoma that is common in young dogs. Unfortunately, an aggressive form of skin cancer known as a mast cell tumor is also possible. The two have the same outward appearance. An infection deep under the skin is also possible. Based on the diagnosis, the treatment will be different. In the meantime, place an E-collar on him to prevent him from licking the area. I hope this information helps!

If this lesion is filled with pus, then it's not a cyst, it's likely an abscess which is a pocket of infection. I would have Zeb seen by the vet for this, as if it is an abscess, it will need to be drained and flushed sterilely, and he will need antibiotics for the infection. The vet can diagnose if he does have an abscess, and can treat him for it.

I would worry that is a precious bite wound from a spider or something or a tumor or cyst that is infected and has a necrotic center. Try to stop in from licking it and clean it with soap and water to rinse the pus off. You can place neosporin to help prevent bacteria and dirt from getting inside. This will buy you time to get to your vet for further testing to see if surgery is needed or just antibiotics

From the pictures, the skin appears red and inflamed. It does look like it is infected. While this may not be a true emergency, I would recommend getting in to see your veterinarian very soon. Pookie will need the area shaved and cleaned up. Your vet may prescribe an antibiotic for this as well depending. Until you can get to your vet, you can keep the area clean and dry and use a mild soap and water to clean the wound. If Pookie is licking it, you can put on ECollar on her to prevent licking.
