Voice for the voiceless keeps silent

This institution has a nice Luke but do not back up what they say they do I found a bewildered and Confused Pitbull in the northern area of Pretoria that was almost killed by a fast-moving traffic I then contacted these people to find out if they can rescue and reunite the Pitbull with their owner or even try to do so I was sent a mail that they do not do these services although I have other dogs I took the risk of taking the dog to my place and tried to locate its owners or an Institute that says there will be the voice for pitbulls it is very disappointing
