puppy boxer health

Question
i just noticed a bump on my boxers right shoulder two days ago and am
wondering if i should have it checked out or wait and see if it goes away? He just
had shots a week and half ago. its not swollen it just feels like a ball in his skin
do you have any ideas on what it could be? thanks

Hi Matt,

It's possible its a reaction to the vaccination, if that's the location of the syringe puncture.  It's always best to have bumps checked out if you aren't sure what they are.  :)  It could be anything from a reaction to a cyst to a tumor.  Just hard to say without being able to see or feel it in person.
