Brush-a-Loves dolls where made from 1987 to 1989 by Tyco. Some are labeled 'AmToy' or 'Matchbox'.
Brush a Loves were pastel colored 10 inch fluffy bear or dog like creatures with brushes on their tails and fluffy straps underneath so the doll could be attached to your arm while you preened it. They also had a mirror attached to their right paw.
The dolls had a scented left paw that was known as the Powder Puff Paw. Each creature's scent was personal to them. Following the success of Brush-a-Loves miniature versions of the creatures were released, these were called Li'l Brush-a-Loves.
