Can anyone come along to the Peakhurst training, or is it for purebreed dogs only (like this website)? I've got a 15 week old LabxGolden Retriever that I'd like to bring along to training at Peakhurst as we live nearby. She's very good at sit, drop, shake hands and 'give that shoe back now you little monster' already, but the socialising should be fun! Do I need to register first somewhere else or can I just turn up at Gannons Park on the first Saturday afternoon I have free (probably mid-March)?
