Is this even possible?? I have a 13 month old lab who has never been particularly keen to walk but thought it would get better - it's not! He walks fairly well in the morning - school run and then off lead by the river and then sleeps most of the day but in the evening I attempt to take him round the block to stretch his legs and he just refuses! Seems happy enough but the minute he sees his lead he runs back to bed!! Should I persist or just be led by him?? First time dog owner still on a steep learning curve...
