Limping

Question
I have a 1-month old male guinea pig named Napoleon who is limping. My brother says he took him outside to run around this morning and Napoleon was fine when he put him back in his cage, but noticed later in the day that he was limping. I just got home from school and his back left leg seems to be able to move normally and he can put a little weight on it, but he holds it tight to his side and limps. Is it just a sprain or broken? What should I do?

Answer
Hello Renata!
Funny, I just got home from school to! Except I was just getting my things from the Grad ceremony! lol
Back to buisness, gentely feel his hind leg, if he squeals, take him to the vet for X-rays. If not, take another day of rest, Check agian.
