Vet in santa ana

I just found a lump on my dog, Jake's groin area.  We have been driving from Philadelphia, PA since January and he has been checked once already so this lump is new.  I know it is not a fatty tumor as it feels completely different from his other one on his chest.  Since we are just passing through, I don't have a vet nor do I know anyone who can recommend a vet in the area.  I obviously have a vehicle so driving is not an issue.  I really would like to have him checked out ASAP.  Any recommendations??

Dr. Anna Herndon  8980-0606-cell / 2582-1706-office. Sorry not to be able to offer any better assistance.
Located 50 meters North of Cruz Rojo (next door to Papa Johns - next to Anatot Gas station) in a small shopping plaza.
Hope this helps.

Thank you so much for the information.  As it turns out I did to call those numbers and received no response, but it was on a Sunday evening.  I will try again...Jake and I thank you!
