I need some serious advice!
Sassy is 3 yrs old. & i think her Leg might be broken or sprained

Last night, she was Rough housing with my other yorkie (Lola) & about an hour later, i noticed Sassy began Limping & would NOT put pressure on her front Leg.
I immediatly picked her up & began moving her Leg to see if there was any Chance it was broken.
She Let me move it around & even allowed me to put pressure on it, without her whining or even snapping at me to stop.
In that case, i dont think its broken.
Which leads me to believe it may be sprained or bruised.
Sassy will walk as LITTLE as possible, & she hops...so that she doesnt put pressure on that leg.
I KNOW THE VET is the BEST ROUTE to take---
However, I am holding off a little longer because i really cannot afford the Xrays & vet Bill right now, or for them to advise me to just keep her off her feet & come back in a few days if she isnt better.
Has this happend to anyone else? If so, do you think this is something that she'll just heal on her own with, in a few days?
PLEASE HELP! I am very worried!
