I dont know what it is its just a brown colour and its sticking up I know its a scale - Like I said im a new owner and kinda going off what I see on the internet which isnt always the best! I saw cases of scale rot start small and get huge and bad ( on the internet) so im kinda worried, I dont know what spurs are? ill show a close up pic. I apologize if im not using the right terminology, I just pretty much want to know what this is and if its bad, harmful, hurts my guy, do I have to go to the vet?! I appreciate the replies. Ill post a close up.
