A tube attachable toothbrush for pets includes an elongate member having a distally disposed head member and a proximal end attachable to a tube of toothpaste. The head member includes an anterior face obliquely disposed relative the elongate member, and a posterior side disposed in a congruent plane with the head member. A clip member, transversely attachable to the tube of toothpaste, is positional to prevent forcing of toothpaste back to spent portions of the tube. An interior channel, disposed between the proximal end and an aperture disposed in the anterior face of the head member, enables fluid communication of toothpaste from the tube to a plurality of bristles disposed upon the anterior face, whereby toothpaste is continuously applicable to a pets teeth and a users hand wielding the elongate member is positioned away from the pets mouth during the act of brushing.
