My dog's benign skin lumps keep reappearing. What should I do?

Updated On September 23rd, 2025

Pet's info: Dog | Mixed Breed Large (61lb +) | Male | neutered | 9 years and 10 months old

I don’t know what breed my dog is. Could you help me out? Also he has two tumors we have gotten them removed and tested before they weren’t cancerous just tissue but he made things worse by gnawing on it. They don’t hurt him either but they just keep coming back is this a medical condition? He also has bad allergies and possible a sinus infection we already give him allergy pills any advice?

Thanks for using Petco Pet Education Center, formerly Petcoach and for looking out for Buddy. I'm not sure from your picture if you're talking about the blackish mass at the front of Buddy's chest, or if he has masses under his skin on his sides. Either way the answer is the same. If the masses are coming back in the same place, then he's either very unlikely or there is local recurrence of the mass. Local recurrence and have been with cancerous growths and also with some more benign types of growths. The appropriate treatment depends on the type of mass that it is. I would recommend asking your veterinarian if he had cytology or histopathology done on the mass for testing (because those would give very different information) and exactly what the growth was. Then you can talk to your veterinarian about the significance of regrowth, or repost a question here if you would like. Another possibility is that he's getting new masses, in similar but not identical places, and it's unrelated to his old masses. For this I would recommend cytology (using a needle to poke the mass while Buddy is awake) at your veterinary office and talking to them about whether removal is needed or not.

    Hi there and thank you for using pet coach to address your concern. Unfortunately it is difficult to say what type of tumors these are with your description and pictures. However, that being said I can see many older pets it will develop a fatty tumors that are benign and will not cause any harm. Unfortunately some dogs are prone to developing multiple fatty tumors over their entire life. As far as the allergies are concerned, I would suggest starting a shampoo such as Douxo PS calm shampoo and bathe twice weekly. Can also recommend starting welactin Omega-3 fish oil and essential 6 Spot On by dermoscent. If these remedies do not help, I would discuss other options with your veterinarian. With options such as apoquel and cytopoint, we are seeing a better response to Allergy treatment these days. I hope this helps guide you in the right direction. Please feel free to contact me if you have any other questions or concerns. I am also available via consultation if needed.
