my girlfriend had one and we stuggled with it too....I think you don't push it...you actually "lift" up the piece that looks like you would push it...??? Do you know what I mean?
P.S. I love pugs too...I have 2
Mimi-Ann, Thanks! got it, definitely a trick to learn! Lift the movable arm though the tendency is to push that piece in. How old are they? My Pugs are 5 girl and 6 boy.
I'm glad you got it....it does look like you should push it doesn't it......
My pugs are 13( Riley, black male) and 10 (Brodie, Fawn male )my two babies !!!!
