174.02 Annotation Public policy does not prohibit insurance coverage for statutorily imposed multiple damages. Cieslewicz v. Mutual Service Cas. Ins. Co. 84 Wis. 2d 91, 267 N.W.2d 595 (1978).

174.02 Annotation Doubling of damages under s. 174.02 (1) (b) operates only after application of the laws of comparative negligence. Sprague v. Sprague, 132 Wis. 2d 68, 389 N.W.2d 823 (Ct. App. 1986).

174.02 Annotation To be a “keeper” of a dog within the definition of “owner” under this statute, the person must exercise some measure of custody, care, or control. An “owner” injured while in control of the dog may not use the statute to hold another owner liable. Armstrong v. Milwaukee Mutual Insurance Co. 202 Wis. 2d 258, 549 N.W.2d 723 (1996), 93-1918.

174.02 Annotation A landlord does not become a harborer of a tenant’s dog by merely permitting the tenant to keep the dog. Malone v. Fons, 217 Wis. 2d 746, 580 N.W.2d 697 (Ct. App. 1998), 96-3326.

174.02 Annotation Armstrong has no application when one who is neither an owner or keeper of the dog is injured. Sub. (1) imposes strict liability on an owner when the person injured is neither the dog’s owner or keeper. Fifer v. Dix, 2000 WI App 66, 234 Wis. 2d 117, 608 N.W.2d 740, 99-1717.

174.02 Annotation An owner may sue a keeper for contribution when an innocent 3rd-party has been injured. Fire Insurance Exchange v. Cincinnati Insurance Company, 2000 WI App 82, 234 Wis. 2d 314, 610 N.W.2d 98, 99-1094.

174.02 Annotation A keeper of a dog may not recover under this section, notwithstanding an allegation that the actual owner was negligent. While the keeper may pursue a common law negligence claim, sub. (1) (b) and its provision of double damages are not applicable to that action. Malik v. American Family Mutual Insurance Co. 2001 WI App 82, 243 Wis. 2d 27, 625 N.W.2d 640, 00-1129.

174.02 Annotation A dog owner does not have notice under sub. (1) (b) because the owner knows that the dog as a puppy chewed on household items in the course of normal teething behavior. Gasper v. Parbs, 2001 WI App 259, 249 Wis. 2d 106, 637 N.W.2d 399, 00-2476.

174.02 Annotation Courts may utilize the traditional 6 public policy factors, formerly referred to as proximate cause, to limit liability in appropriate cases under this section. Fandrey v. American Family, 2004 WI 62, 272 Wis. 2d 46, 680 N.W.2d 345, 02-2628.

174.02 Annotation Public policy does not preclude a police officer from suing for injuries received because of a dog attack that occurred during the course of the officer’s duties. Cole v. Hubanks, 2004 WI 74, 272 Wis. 2d 539, 681 N.W.2d 147, 02-1416.

174.02 Annotation Under s. 174.001 (5), “owner” includes anyone who keeps or harbors a dog. The concepts of “harbor” and “keep” are similar, and the liability of one who harbors a dog and one who keeps a dog is the same. When a homeowner has become a statutory owner by virtue of the dog’s living in her residence for several months, that status does not vary on a minute-to-minute basis, depending on which person controls the dog. The homeowner’s status as a harborer of the dog is not extinguished when the dog’s legal owner takes momentary control of the dog. Pawlowski v. American Family Mutual Insurance Co. 2009 WI 105, 322 Wis. 2d 21, 777 N.W.2d 67, 07-2651.

174.02 Annotation Mere ownership of the property on which a dog resides is not sufficient to establish that an individual is an owner of a dog under this section. The totality of the circumstances determines whether the legal owner of the property has exercised the requisite control over the property to be considered a harborer and thus an owner under the statute. Augsburger v. Homestead Mutual Insurance Company, 2014 WI 133, 359 Wis. 2d 385, 856 N.W.2d 874, 12-0641.

174.05(2) (2) Tax. The minimum dog license tax is $3 for a neutered male dog or spayed female dog, upon presentation of evidence that the dog is neutered or spayed, and $8 for an unneutered male dog or unspayed female dog, or one-half of these amounts if the dog became 5 months of age after July 1 of the license year.

174.05(3) (3) Additional tax. The governing body of any county may by a majority vote of the members present at any regular meeting raise the minimum dog license tax on dogs within its jurisdiction and the governing body of any town, village or city may by resolution raise the minimum dog license tax on dogs within its jurisdiction. If the governing body of any county, town, village or city increases the minimum tax, it shall provide that the tax for unneutered male dogs and unspayed female dogs is greater than the tax for neutered male dogs and spayed female dogs. The additional tax may not exceed the total cost of all dog licensing, regulating and impounding activities for the previous year, less any refunds which may be received under s. 174.09 (2), and shall be levied and collected in the same manner as other dog license taxes.

174.05(4) (4) License year. The license year commences on January 1 and ends on the following December 31.

174.05(5) (5) Late fees.

All late fees received or collected shall be paid into the local treasury as revenue of the town, village or city in which the license was issued. The governing body of any county, town, village or city may, when setting the amount of the tax, provide that any person purchasing a dog license for a dog 5 months of age or over after April 1 shall pay an additional late fee.

174.053 174.053 Multiple dog licenses.

174.053(1) (1) Multiple dog license option. Any person who keeps more than one dog may, instead of the license tax for each dog required by this chapter, apply to the collecting official for a multiple dog license for the keeping of the dogs. Such person shall pay for the license year a license tax of $35 for 12 or fewer dogs and an additional $3 for each dog in excess of 12. Upon payment of the required multiple dog license tax and upon presentation of evidence that all dogs over 5 months of age are currently immunized against rabies, the collecting official shall issue the multiple dog license and a number of tags equal to the number of dogs authorized to be kept by the person.

174.053(2) (2) Multiple dog license tags. Multiple dog license tags shall be made in a form so that they may be readily distinguishable from the individual license tags for the same year. The owner or keeper of dogs for which a multiple dog license has been issued shall keep at all times a multiple dog license tag attached to the collar of each dog over 5 months old kept by the owner or keeper under a multiple dog license, but this requirement does not apply to a dog during competition or training, to a dog securely confined indoors, to a dog while hunting, or to a dog securely confined in a fenced area. An owner or keeper may transfer a multiple dog license tag from a dog that the owner or keeper no longer owns or keeps to another dog if the other dog is currently immunized against rabies. The rabies vaccination tag or substitute tag shall remain attached to the dog for which it is issued at all times, but this requirement does not apply to a dog during competition or training, to a dog securely confined indoors, to a dog while hunting, or to a dog securely confined in a fenced area. No dog bearing a multiple dog license tag shall be permitted to stray or to be taken anywhere outside the limits of the owner’s or keeper’s premises unless the dog is in leash or temporarily out for the purposes of hunting, breeding, trial, training, or competition.

174.053(3) (3) Applicability of other requirements. Unless clearly inapplicable, all the provisions of this chapter relating to the individual dog license tax, licenses, and tags shall apply to the multiple dog license and tags.

174.054 History History: 1983 a. 451.

174.055 174.055 Exemption of certain dogs. Every dog that is a service animal, as defined in s. 106.52 (1) (fm), is exempt from the dog license tax and every person owning such a dog shall receive annually a free dog license from the local collecting officer upon application.

A listing official who is a full-time, salaried municipal employee shall receive this compensation from the county board but shall be required to pay the compensation into the town, village, or city treasury.

174.06(3)(b) (b) In a county in which an agreement under s. 174.10 (2) is in effect, the intergovernmental commission shall pay the compensation required under par. (a).

174.06(4) (4) Cooperation with listing official. Every person shall answer frankly and fully all questions asked by the listing official relative to the ownership or keeping of dogs within the district.

174.06(5) (5) Records.
