Advice for 2015!

This sheep and sign above are in the Joules department of our local department store (think Grace Bros in Are You Being Served). Not sure what connection there is between a sheep and pig powders! Not even sure what pig powders are, but sound necessary, if you are a pig. And who is Dennis?
'Baa'filing, however, as to the connection with Joules women's wear (my better half was trying on a top) and pig powders!
