Dog Lost Castle Park Estate (near National Basketball Arena)

Our Dog got out on Sunday 25 of August. He hasn't been home since. He has only come from having an operation on his back right leg and needs his medicine. He is sadly missed by all the family especially my special needs son. He is a male and is 3 yrs old. He is a cross German Sheppard / Collie. I would be very greatful if contacts made if found / seen.
