My mum did for that reason too, but she also hid the puppy under her jacket because when you have a puppy everyone stops to talk to you and my mum likes a chat but it gets ridiculous (and she actually had 2 puppies, just one was about 6 weeks older than the other, so she had double the attention) - and we all know that attention is why Babs flaunts her puppy sling!My friend had a puppy sling thing as she had another dog to take for a walk and so puppy came along. I think that's the only situation that makes sense??
