Small pebbles.

The vets laugh when they see Wilf again . A regular and welcome patient . He gets not one , but two , kisses on his head from each of them - even the stern Parisienne . After an hour on the table we learn that what we thought was an eye infection is actually glaucoma . A common side effect of diabetes. Who knew that you could be blind, have cataracts and develop glaucoma ? The good news - still no pain - just a gradual slowing down and wearing away. There's no doubting that a change is taking place .

After an hour on the table the family fellow was taken off to be spoilt . Twenty minutes later , face stained yellow from the phenol drops, he finds himself at the new McDonalds by the motorway exit . Surrounded by his pack, eyes bright , aching limbs forgotten , the smell of french fries . There is nothing like a sliver of quarter pounder with cheese to bring a smile to an old boys face . There comes a point in every dogs life when the rule book should be thrown away .

Through the sunflower fields this morning . He's happy to follow along close behind . As all PONs know : - ' Nobody trips over mountains . It's the small pebble that causes you to stumble ".
