ABSTRACT:
A dog brush is provided for attachment to a conventional vacuum cleaner. Semi-flexible plastic bristles are curved in the direction in which the brush is drawn across a dog, whereby to cradle loose hairs transversely of the air flow into the vacuum cleaner, and thus most efficiently to pull the loose hairs into the vacuum cleaner. Restrictive orifices are provided to increase velocity of air flow further to facilitate picking up loose hairs. The handle of the brush is oriented for most efficient brushing of a dog.
