Haley,
How are the injections going? Are you altering the spot? Aslong as you do that there will not be any scaring tissue.Ourvetsay out 4-5 sq inch area is ok. Most buns dontmind the shots to the upper back, towards the neck, Penny is reallystill if we do it little bit to the side, either way right orleft.
How is the wound, if it hasn't showed signs of pus by now, I think you are in the clear.
