Lovely Onxy came into our care when we were doing a spay campaign in the village a few months ago. We took his sister Opal into our care as she was so friendly without realising her brother too was on the street. Both must have been dumped as pups. A kind lady was feeding them.  We rushed back to pick up Onyx and reunite him with his sis. Opal was quickly adopted.  
Onys will need another friendly dog in the home as he has become a little shy. Once he knows you and is comfortable around you, this all changes. Onyx is not very big  - springer sized.
