An original procedure using a load cell with an amplifier, an oscillos
cop and a printer, enabled us to measure maximal pulling strength deve
lopped by six military dogs during fighting exercises. The maximal pul
ling strength measured, with four canine teeth in action, varied from
1000 newtons to 1120 newtons according to the direction in which the d
og pulled. The animals pulled in a unique direction, standing on their
four limbs, and thus using their total muscular capacity. The pulling
strength intensity decreased with repetitive efforts. These results m
ay contribute to the elaboration of specifications for prosthetic reco
nstitution of canine teeth fractures.
