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!
