My puppy has a perfect circular sore on his leg. What could it be?

Thanks for using Petco Pet Education Center, formerly Petcoach! This could be due to ringworm. This could also be just a focal skin bacterial infection or secondary to an injury that has not healed, among other possibilities. You can use an e-collar to try to prevent further self trauma. I recommend that you have Tink evaluated by your veterinarian for further assessment and treatment. They would be able to check for these possibilities and treat accordingly. Ringworm can be transmitted to humans so just in case this is what is going with Tink, wear gloves when handling this lesion. Good luck and best wishes!

Hi and thanks for using Petco Pet Education Center, formerly Petcoach! Sorry to hear about Yeti. This area resembles a localized skin infection most likely caused by a bacteria that normally lives on his skin. It is quite red around the area so if you notice that these areas are spreading, getting worse and not improving, you should have your veterinarian evaluate Yeti. They can get a thorough history and then examine Yeti and the affected areas. Skin problems have many causes including bacterial infections, allergies, flea/tick/insect bites/stings, trauma, fungal infections, problems with mites, or even internal problems that present with skin involvement. Your vet can advise whether diagnostics are needed (skin tests, blood tests, etc) or if a treatment plan is indicated based on what they observe. Good luck with Yeti.

This looks like it could be a pressure sore from King lying on a hard surface a lot. Make sure he has a soft bed to lay down on. Keep an eye on it, and if it gets bigger or it appears to bother him (he starts licking or chewing at it), have him seen by a vet. Best of luck.

This kind of lesion/blister needs to be ideally assessed by your veterinarian to have a definitive and specific answer. Usually there are two ways your vet can do that a part from examining it directly during physical examination. A biopsy can be taken under local or general anesthetic, otherwise a smaller sample through a fine needle can be aspirated (this technique is called FNA= fine needle aspiration). Differentials include skin cysts, infections, benign or more sinister type of tumors. Hope this answer was helpful, but please do not hesitate to contact us again on the forum or by requesting a consultation if you have any more questions or to discuss it any further.

Thanks for using Petco Pet Education Center, formerly Petcoach! This looks like a small focus of infection. It could be due to allergies or even just secondary to minor trauma. You can try to shave around it and clean it. If it continues to look superficial (as it looks on the picture), you can consider applying a thin film of triple antibiotic on it in case it is just a mild infection. If it does not resolve within 1 week of starting such treatment, have him evaluated by your veterinarian for further assessment and treatment. Good luck and have a good night!

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!

This could be an allergic reaction, a skin infection (bacterial or yeast) or even a skin tumor. You should have it examined by your veterinarian, as it is not possible to distinguish these by just looking at a photo. An bacterial skin infection can usually be treated with antibiotics , a fungal infection (yeast) with a fungicidal medicine. To identify a tumor, your vet may want to do a fine needle aspirate (he takes some material from the area in question with a needle and then looks at it under the microscope) to determine whether this is concerning.
