The needle is bigger and you could always ask for them to use a topical anesthetic cream if you're concerned about it being painful (not sure that it would make that much of a difference though). But it's over so fast that I'd personally be okay just having done in the office like a normal vaccine. I think it'd definitely be worth it and safer to go ahead and get him chipped now without anesthesia than waiting for another procedure in the future that requires it. |
