HELP PLEASE! Ezra injured - need help in Alexandria VA! Visiting my son for birth of granddaughter (yay). While playing with 2 other dogs Ezra suddenly started screaming in pain and is now 3-legged lame on right front (1 hr). No obvious injury/pain point. Home is far away in CT. Need good vet reference (obviously preferably sight hound experienced) in Alexandria ASAP please. Very very worried. Thank you.
