Dogs and Nappies?

[billmoseley]

Today as it was wet and miserable we decide we would have a trip to Wick to pick up supplies. I ventured into Pets at home and was looking round when i saw to my disbelief Nappies for dogs! why? A dog does it's business outside when it being walked. I came up with only 2 reasons why you might need them.
1. You live somewhere that you can't walk your dog. In that case you shouldn't have one.
2. The dog is poorly and can't control it'self. In which case seek a vets advice?
Can any one else think of a good reason for them?
