Mr McClay said he was horrified by the attack on Sakurako.
"I want to applaud the Murupara community for rallying to support her family and have been talking with Local Community Board chairman Jacob Te Kurapa to see how the government can help them further.
"Whilst Parliament has banned the importation of a number of dangerous and aggressive dog breeds as well as given tools to councils to create local rules to control dogs, there are still far too many serious dog attacks in the Bay of Plenty."
Mr McClay said responsibility lay in part with dog owners.
"However, I'm keen to work with the four councils in my electorate to see what more can effectively be done to help control this serious problem.
"Sadly bans won't always work as few of these dogs are pure enough to identify as one specific breed or another. In many cases it seems clear that some irresponsible owners are purposely breeding dogs for their aggressive traits and this is of particular concern."
Local Government Minister Paula Bennett said she was considering whether dog control regulations needed to improve.
Police are investigating the attack.
