Troublesome 2's!

Percy has reached 2 years old and has suddenly decided that it's ok to test me! He has started "yapping" on his walk - even if no one is around! If I tell him off, he keeps about 2 feet away from me! So drastic measures were needed and I bought a vibrating collar.

Put it on him today and I only needed to do the warning bleep and he stopped.

So I don't know whether to be pleased that it has worked so quickly without the need to punish him, or whether to be annoyed as he has obviously been understanding my commands all along and is just being bloody minded!!
