Jimmy turned 2 back in December and really seems to have calmed down (mostly). I haven't noticed it happening as it's been so gradual, but other people keep commenting on it.
To be honest all he does is sleep all day now, neither Misty or myself can stir him into action for any length of time before he's sprawled out on his back again.
He's as eager as ever to go on walks and as active as ever on them, so I don't think there's a problem.
Is this what Cockers do when they hit this age ? I must admit I'm slightly envious, he looks to have a great life.
