Lost dog spotted on The Avenue, N8

I was driving back last night around 10pm and spotted this dog. No collar. Wary but friendly. I stopped to see if I could help it but it ran off . Muscular but looked thin. I think a female. Deifniltey not with anyone. I am based in Bowes Park so I wonder if any ok be on this forum  lives around there and have street what’s app groups you can share with . I spotted I on corner if Hornsey Par Road and The Avenue N8. Then it ran off down the Avenue. The dog looked a bit paler brown IRL. Thanks
