Daisy's Mom, bless you for taking pity on a poor Brit who doesn't understand the language - thank you.

O.K. First of all, and I think I remember seeing this somewhere else here, 7 years to 1 is not the correct ratio. It goes something like the first year for a dog is the same as nine for a child, the second is around 9-7... it varies from dog to dog but do not be fooled by the seven year itch - I mean rule!

Second...If your dog has been doing this for fourteen years then, I'm sorry but, whatever the initial reason for this behaviour is kinda lost and at the age the dog is you probably will cause more stress trying to correct it than living with it.
