My dog has a red, nickel-sized lump with black pores. Is it serious?

Thanks for using Petco Pet Education Center, formerly Petcoach! This could be a benign or malignant growth. There is no way of knowing what it is just based on its appearance. Common tumors in this region include melanomas, squamous cell carcinomas, mast cell tumors and soft tissue sarcomas, among others. This is often differentiated by a test called a fine needle aspirate (FNA) which is a pain free, inexpensive and easy procedure which in most cases will help reach a diagnosis. Sometimes a biopsy is needed for a definitive diagnosis. I recommend that you have him evaluated by your veterinarian for further assessment and treatment. I am really hoping for something benign. Good luck and have a good night!

From the picture this looks to be a mass. I would recommend having it evaluated by your family vet for needle sampling with cytology. That way they can determine if this is a mass and if so if it needs to be surgically removed (benign vs malignant). The toe is a tricky location so having it evaluated while it is small would be best. I hope this helps and thank you for using Petco Pet Education Center, formerly Petcoach!

I hate to hear this is happening to your pup! I recommend to have her examined by the veterinarian. Skin masses can be many things but red raised masses are especially concerning for a skin cancer called a Mast Cell tumor. Your veterinarian will need to collect a sample of cell to examine under the microscope to determine what this is and if further treatment is needed. another common reason for a lesion like this is a foreign object trapped under the skin. Fox tails have a tendency to do this and generally need to be removed and the lesion lanced. Have this checked out soon. Protect the area from licking by having Dog wear an elizabethan collar at all times. I hope this helps.

Unfortunately, I can't say that I like the looks of that. Masses like these associated with the nail bed can often be problematic in both structure and physiology. structurally, they can grow larger and start to make it difficult for Lily to walk normally without pain. Physiologically, there are types of toes masses that malignant, both locally and systemically, and others that are benign. The first thing I'd do if you are interested in doing a work up, would be to request your vet obtain a biopsy or cytology of the lesion to assess what it is. Depending on the result and how fast they believe the lesion will grow, your vet can make appropriate suggestions. In the majority of toe masses that have any potential at all for spread, typically the toe (or toes) are amputated. Dogs get along fine and usually don't miss a step, even in older pups like Lily. Anyway, hope this helps.

I am sorry to hear about Rocco. This looks like it could potentially be a tumor that has a small ulceration or wound. We can have tumors that are benign and do not spread/cause other problems, but others are aggressive and should be removed. I would recommend bringing Rocco into the vet for an exam. Your vet may try to get some cells from the tumor to examine under the microscope in order to determine the type/behavior of the growth and determine if it should be surgically removed or if it can just be monitored.

I recommend to take Greta to see her veterinarian. While most skin masses are benign, masses that a red/pink, hairless and raised are a concern for a malignant skin tumor called a Mast Cell tumor. It also appears as though this mass is ulcerated regardless and it needs to be removed. Once masses grow to the point of ulceration, they will heal and break open over and over again which can make them prone to infections not to mention oozing/bleeding. Just like with a human, the doctor will likely take a sample of the mass or remove the mass entirely and microscopically exam it. Thats the only way to know what it is accurately. In the mean time, protect the mass from trauma and wash it daily with an antibacterial hand soap (rinse it well). You can apply a small amount of coconut oil and rub it well into the skin. This may help the wound to heal a little faster. I hope this helps to point you in the right direction. Please feel free to post any further questions!

Hello and thank you for using Petco Pet Education Center, formerly Petcoach. A growth like Spike has on his toe could be related to infection, a benign mass like a cyst, but unfortunately it could also be a cancerous growth. It would be best to schedule a visit to your veterinarian so that he or she can obtain a small needle aspirate sample from the growth and decide if it is cancerous. A lot of growths on the toes can be cured if removed surgically. I hope for the best outcome for Spike!
