What you need:

1 wooden board
5 hooks (single, double and triple)
screws and a screwdriver
masking tape
acrylic paint

Protect the edges of the board with the masking tape and paint the centre of the board.
Leave to dry. Arrange the hooks and fasten with the screws.
Hang the board by the entrance door and hang a leash, a towel for paws, a canine raincoat, brushes…
And everything you need for your four-legged pet will always be on hand.
