I am in Leicestershire too.
We would love to meet up with you all. Tilly adores all dogs, but particularly cockers, of course! She is 10 months old now. Bradgate Park is just 10 miles away, so would be great. Another suggestion might be Burbage Woods, just off the M69, but may not be so central for everyone. It's very safe for dogs and there is a farmhouse there selling hot chocolate and ice-lollies, great whatever the weather!
Would be very happy to be involved in organising and meeting up.
