"We were making sure the dog was back at 100 per cent and everything seems fine. The dog has good strong character and showing no adverse effects."
The stabbing happened on only the duo's second job on duty since they graduated on December 6.
McLeod said dog handlers were aware of the dangers of the job but were well trained and prepared for work on the front line.
"Handlers asses the situations they are called to and consider what tactical decision to make. From time to time dogs do get injured and that's one of the risks we accept.
"The dogs are trained to perform at that level and we are confident they will do the best they can."
