The car park at the country park was full so I parked down a nearby lane. As I got out of the car I realised I was a bit too close to this spikey bush - not sure what it is but it sticks to fur as Finlay found out!!
I agree with @Cherrill. They are a nightmare to pull out of my Goldens fur. They usually end up getting a very unattractive haircut because I don't have the patience to pull them all out by hand :-( You've found a way to make them look attractive, though. Very nice composition.
