Embodiments of a dog restraining apparatus comprise a dog collar and a collar positioning assembly. The collar is configured to attach to a leash at a location behind the dog's head when the collar is secured around the dog's neck. The collar positioning assembly includes an alignment strap having ends attachable to the collar at respective collar attachment locations such that the alignment strap is extendable across the dog's nose bridge when the dog collar is secured around the dog's neck The collar attachment locations may be adjustable along the collar. The alignment strap may have a continuous or non-continuous bead of elastomer disposed on its interior surface to frictionally engage the dog's nose. The collar positioning assembly may be readily detachable from, and re-attachable to, the collar. Attachment of the strap ends may be facilitated by intervening structures such as strap end loops, O-rings and releasable collar attachment loops.
