I've trained my mind so that it doesn't spend the majority of its time in the heightened state of anxiety that I once viewed as normal. So now there's plenty of space between the old ears to ponder the important philosophical questions of life. And one came to me to me the other day as I was driving through Windy Corner, the gateway into Brixham. 'How do I know that a dog is a dog?'
This picture illustrates the point nicely. If a affable alien invader came to Earth and during a chat I told them that these creatures were of the same species he'd say that I was having a laugh. I can't figure it out. They're all so blooming different. I had an idea that it might be to do with the eyes but then have a look at huskies.
This lead onto another question. So how does a dog recognise another dog of a different breed? I thought that it must be down to that keen sense of smell that our canine friends are supposed to have. But a little research around the subject suggests otherwise. Follow the link to read this Scientific American article reporting on a pertinent experiment. It seems that dogs can pick out each other from photos. No distinctive doggy odour involved!
