Lost Dog "Jack" Yorkie Terrier South Buffalo in Buffalo, Illinois

Jack and I were walking down South Park near Lockwood when he got away from me and I couldn't catch up to him. He is super friendly and very loved but he is a runner. We miss him terribly. He was still attached to his leash. He has a collar on with a tag but the tag has my old number on it (868-xxxx) My new # is 864-xxxx, ask for Kenny or Nancy. Please call me or respond to this post if you saw him. I have checked all the shelters daily and he still has not been found. He went missing on Sunday, June 12th, He is a small yorshire terrier, brown, black and grey. His brother "Georgie" is upset without him.
