Waar is Max? - Jan van Haasteren Expert Puzzle (500)

Jan van Haasteren Expert is a puzzle series for the advanced puzzler. Expert puzzles are challenging, comical illustrations, in a comfortable size of 500 pieces. Don't be fooled though; in this new series the difficulty is not determined by the number of pieces, but by the illustrations! As in every Jan van Haasteren puzzle, the Jan van Haasteren family is at the center. In each Expert puzzle, 1 or 2 well-known characters from the family will go on their own little adventure!

Mother-in-law and Father-in-law are taking a walk with their faithful four-legged friend Max.
It is very busy in the park to Max's delight, will Mother-in-law and Father-in-law ever be able to find him again?
