In case the defendant is not satisfied with the amount specified in the bond or with the surety, the defendant may, upon 5 days’ notice to the plaintiff, apply to a judge for additional security and the judge may require the plaintiff to give and file another bond, to be approved by the judge, in such sum as the judge shall consider proper, not exceeding the appraised value of the property attached. The surety shall justify as provided in s. 811.06; but if there be more than one surety, the sureties may be accepted if they are jointly responsible for the required sum.
