No company in the US has rights to Wolfblood, as of April 2015. It is only possible to watch it for free online in the UK and associated territories by using BBC services. However, six episodes of the latest series are available on CBBC.
The CBBC website also offers exclusive webisodes and additional material for fans who are able to access it. The BBC has no plans to release the rights for later episodes in the US, according to DisneyTube, and fans may have to resort to purchasing DVD copies of the episodes to access them outside of the UK.
