Another pug 'sister' here - my mum has two (and a rescue maltese/spaniel). They spend alot of time with my two boxers. I love all the little flat faces! Naughty naughty little dogs! Very lovable and sweet though.
Furminator works great for them!! Get one!! You can also get a cheaper variety from the rspca world for pets shop, works good on my cats. Mum has the real Furminator for the pugs though.
