Dog rose

I need to prune this bush but the stems are a bit scary with all those thorns, probably a good burglar deterrent though.

Thank you for all your kind stars and comments about my 4,000 blips.  I wrote after my first week that I didn't think I would last the pace.... I have missed a few but not so much recently.  I also think I have people I know "trained" so that when I say I have to get my blip for the day they know what I mean.  Long may Blip continue.
