What does "VIGYAZZ A MOSOLYGO KUTYA" mean in Hungarian?

Question

Someone I work with wrote, "VIGYAZZ A MOSOLYGO KUTYA". What does it mean?

Answer 1

Actually this doesn't make sense in hungarian.
It should be like this: "Vigyázz a mosolygó kutyától." or "óvakodj a mosolygó kutyától."
Something like that: Beware of the smiling dog

Answer 2

It means: Beware of the smiling dog.
Vigyazz = beware, look out
a = the
mosoly = a smile
kutya = a dog.
It's like the line from Shakespeare:
One may smile and smile and be a villain.
