Hi Kat.
I know of one or two but you need to check if they're still running as it's a while since I attended them.
General dog/puppy training classes at Hoghten & Clayton Brook ( personally I didn't like the woman who ran the Hoghten one, my Skyes never forgave her for squirting water in their faces
) & more specific ringcraft training classes in Wigan( at Highfield) & at Wheelton.
The Wheelton one is just for small breeds while the Highfield one is for all breeds so much busier. I've attended both & they are both very good. I would say the Highfield one is more professional, gives a good grounding & gets your dog mixing with all size of others, whereas the Wherlton one is smaller, more intimate like a local club. They are both very friendly & welcoming.
