Answer:
a. same side as the veterinarian.
Step-by-step explanation:
It is important, when performing an examination on a horse, to ensure that it is held, rather than tied. Moreover, both the handler and the veterinarian should stand on the same side of the horse. If any of the people move to the other side of the horse, all people present should move as well. If holding a horse becomes particularly difficult, chemical restraint can be considered.
