Sunday Stamps: This week's theme is canines. Please see See It on a Postcard for more contributions.
I have shown this stamp before on my blog, back in 2012 so I hope you don't mind if I show it again. This stamp is from Hong Kong and pictures an English Springer spaniel. These dogs can be working dogs, trained as 'sniffers' for explosives or contraband, and I believe that is what is being shown here.
See today's prompt for more canines!
