Teaching an old dog new tricks

Luke is really intelligent, he is very quick to learn and is very keen especially if there is food involved as a reward.
He sits beautifully , fetches and leaves his ball or toy, and can now lie down and also roll onto his back . His walking on the lead is much better too, he really is a good boy.
he does most of his commands now to just hand signals, he really is a joy to teach and always looks so happy , look at his face on the photo !
yesterday while we were out shopping we came upon a stand with volunteers from he north east springer spaniel rescue, they do brilliant work too and were selling home made dog treats all different flavours, like peanut butter and banana , tuna and many others, well I bought some for Luke and wow he thought they were delicious, so if anyone has any recipies for these I'd be very grateful, then I can make him some.
Enjoy the good weather everyone and remember our animals need protection in the sun just like us, so its sun block on noses time :)
