Hello, sorry to hear about Bear. Its difficult to tell exactly what that is without looking at the structure and what makes up the little nodule. That is, the cells forming the little nodule would need to be evaluated to tell exactly what that is. Given that it is a small area, it could be removed and submitted to biopsy to determine the cellular make up. Alternatively, you can monitor to see if the nodule resolves. If it goes away within a few days, then this is likely nothing of big concern. More severe things this could represent such as cancerous tumor can begin by looking like this. If this is indeed something more aggressive, then it may continue to grow and get worse. If so, then this should definitely be evaluated by their veterinarian. Please keep a close eye on this nodule, it should begin to improve within a few days, otherwise have your this further evaluated by your veterinarian. Hope this helps and best of luck.

    This looks like an injury or an irritated growth from your photo. It’s fairly small and appears to be in the skin so if needed they can easily remove it. I’m not overly concerned about it, but I’m glad you’ll be taking him in to make sure it’s nothing serious. Thanks for using Petco Pet Education Center, formerly Petcoach to help you care for Bugsy.
