In which I mess it up again!

Jenny took me out for my usual walk today. It was a bit later than usual but we set off on one of my favourite walks, around the valley. When we go on this walk, Jenny takes the long lead and lets me have a bit of a run and a good sniff at all the lovely smells around there. We met two ladies with four littles westies and I was very good. I let them sniff around me and didn't try to jump on them or bark at them at all. I think Jenny was very pleased with me for that. Later we met another little white dog and again,  I was on my best behaviour. So far so good, but then we met a family with a big brown dog on the way back and I'm afraid I slipped - just a little bit - well, rather a lot actually, although I couldn't help it, you know.
Jenny had pulled me over to the grassy bit at the side of the path so that the family could pass but I just couldn't resist having a bit of a bark and a leap towards that other dog. Unfortunately, I took Jenny by surprise and the next thing I knew, I seemed to be pulling a heavy weight. When I looked behind me, I saw Jenny lying full length on the ground! Imagine that! A little dog like me being strong enough to pull her over! I don't think she was very impressed though and I got a smack.
Later, I heard her telling Keith about it. He was much more angry than she had been. I think I heard the words 'rescue centre'. I hope that doesn't mean he wants to send me back. I think I'd better keep a low profile for the rest of the evening.
Doesn't look as if I'll be getting any biscuits tonight either.....  (sigh)
