My 6 year old, Ellie, and her cocker friend from next door, Toffee, have been out on a long walk with us today and had been walking for 5 hours when we were cutting through a park close to home. There were 2 other cockers there to play with and Ellie, after saying hello, ran round and round in circles barking and barking. All I could do was look at OH and say 'wouldn't you think she would be tired'.
She did crash out when we got home though.
