OPINION
Paula Leever, a sheriffs deputy, appeals from the district court’s order granting summary judgment in favor of her employer, Carson City (the “City”), and denying her own motion for partial summary judgment. Leever sued the City for unpaid overtime wages pursuant to the Fair Labor Standards Act, 29 U.S.C. §§ 201-219 *1016 (“FLSA”), alleging that the City failed to compensate her for overtime work spent caring for her assigned police dog. The City contends that it was exempt from the overtime provisions of the FLSA pursuant to 29 C.F.R. § 785.23 because it had a “reasonable agreement” to compensate Leever for her overtime work by way of a biweekly flat fee. Leever contends that she did not have an agreement with the City, and that, even if she did, the agreement was not reasonable as a matter of law. We have jurisdiction pursuant to 28 U.S.C. § 1291, and we reverse and remand.
BACKGROUND
Leever began her career as a deputy with the Carson City Sheriffs Department in 1992. Leever was assigned to “canine” duty in 1995. As part of her responsibilities as a canine officer, Leever was required to care for and kennel her assigned police dog, “Scout,” during her off-duty hours. Leever was responsible for grooming, feeding, bathing, and exercising Scout, and for maintaining Scout’s physical and mental health. In addition, Leever was required to clean Scout’s kennel regularly and expend extra effort to keep her own home clean due to the presence of the dog. Finally, Leever was required to spend off-duty hours training and socializing Scout in order to maintain Scout’s fitness as a police dog. Leever claims that, on average, she spent 28 off-duty hours per week caring for and training Scout. The City assigned Leever an official vehicle to transport Scout to and from work, and it paid all of the costs associated with caring for and feeding Scout.
The City knew that Leever spent off-duty time caring for and training Scout and it admits that caring for and training Scout was compensable work under the FLSA. Rather than pay overtime wages, however, the City agreed to compensate Leever for her overtime work by way of a flat-fee salary differential. In 1995, the City and the Carson City Sheriffs Protective Association (the “Union”), which is the exclusive bargaining agent for Sheriffs deputies employed by the City and of which Leever is a member, negotiated a salary differential of $60 per bi-weekly pay period as compensation for the off-duty hours spent by canine officers working with their dogs. The term was incorporated into the 1996-99 Collective Bargaining Agreement (“CBA”) as follows:
CANINE OFFICER: An officer permanently assigned to canine duty shall receive a salary differential of $60.00 per pay period [2 weeks] for the care — and feeding of a dog.
The City did not ask Leever how much time she spent caring for Scout during her off-duty hours or attempt on its own to approximate the number of off-duty hours worked by canine officers when arriving at the salary differential. Rather, the City intended to establish a “flat-rate enhancement” for canine officers “in recognition of their jobs.” In determining the amount of the salary differential, the City relied on figures it obtained from an informal survey of the compensation other Nevada law enforcement agencies provided to their canine officers.
Leever sued the City, alleging that she was entitled to overtime pay pursuant to the FLSA for her off-duty hours spent working with Scout. At the close of discovery, the City moved for summary judgment on the ground that it was exempt from the overtime provisions of the FLSA because it had a “reasonable agreement” under 29 C.F.R. § 785.23 with Leever to compensate her at a flat rate for her overtime work caring for Scout. Leever opposed the City’s motion and moved for partial summary judgment as to the City’s *1017 liability on the ground that § 785.23 did not apply because she never agreed to accept a flat fee as payment for her overtime work and that, even if she did, the agreement was not “reasonable.” The district court granted the City’s motion and denied Leever’s. Although the district court recognized that the salary differential was the equivalent of only one hour’s pay per week, which was “insufficient for the tasks involved” in caring for and training Scout, it found that the agreement was reasonable as a matter of law primarily because it was negotiated at arms-length between the City and the Union. Leever timely appealed.

ANALYSIS
I.
The FLSA requires employers to pay overtime wages equal to one and one-half times the employee’s regular rate for' work performed in excess of 40 hours per week. 29 U.S.C. § 207(a). Law enforcement employers are governed by a slightly more permissive regime for computing overtime hours. See 29 U.S.C. § 207(k). The City does not dispute that Leever spent off-duty hours caring for Scout in addition to the work she performed during her 40-hour work week, and it concedes that caring for Scout was compensable work under the FLSA. 1 The City contends, however, that it was exempt from the overtime provisions of the FLSA pursuant to 29 C.F.R. § 785.23. 2 That regulation provides an exemption from the overtime pay requirement for employers whose employees work from their homes for extended periods of time, such that it would be difficult to compute the exact number of hours actually worked by the employee. Id. In those circumstances, an employer and an employee are permitted to agree on an alternative means of compensating the employee for overtime work, so long as the agreement is “reasonable” and takes into account “all of the pertinent facts.” Id. The regulation reads, in relevant part:
*1018 Employees residing on employer’s premises or working at home.
An employee who resides on his employer’s premises on a permanent basis or for extended periods of time is not considered as working all the time he is on the premises. Ordinarily, he may engage in normal private pursuits and thus have enough time for eating, sleeping, entertaining, and other periods of complete freedom from all duties when he may leave the premises for purposes of his own. It is, of course, difficult to determine the exact hours worked under these circumstances and any reasonable agreement of the parties which takes into consideration all of the pertinent facts will be accepted.
Id.
Thus, in order to qualify for the exemption, the City has the burden of proving, “plainly and unmistakably,” that (1) there was an agreement to compensate Leever for her overtime work caring for Scout, and (2) the agreement was “reasonable,” having taken into account “all of the pertinent facts.”
See Brigham,
II.
At the outset, Leever contends that she did not have an agreement with the City to be compensated for her overtime work caring for and training Scout. The City has shown otherwise. Although the City did not negotiate the salary differential with Leever directly, it negotiated the 1996-99 CBA with the Union, which was acting as Leever’s representative and exclusive bargaining agent. Leever contends that because she was not invited to participate in the negotiations, she never agreed to the flat fee. She relies on
Holzapfel v. Town of Newburgh,
III.
The City failed, however, to show that its agreement with Leever was “reasonable” as a matter of law. Although this circuit has not yet ruled on the meaning of “reasonable agreement” under § 785.23, three other circuits have interpreted the regulation in circumstances similar to the facts of this case.
In
Holzapfel,
a canine officer claimed that he spent up to 45 off-duty hours per week working with his assigned police dog, “Bandit.”
Holzapfel,
In
Rudolph v. Metropolitan Airports Commission,
Leever contends that the salary differential agreement was unreasonable as a matter of law because it failed to take into account the number of hours she actually worked. We agree that the agreement cannot be held to be reasonable as a matter of law. Apart from stating that “all of the pertinent facts” should be taken into consideration, the regulation does not specify what facts must be taken into consideration when forming an agreement under § 785.23. The eases interpreting the regulation, however, suggest that, at a minimum, an agreement must take into account some approximation of the number of hours actually worked by the employee or that the employee could reasonably be required to work.
See Rudolph,
There is no evidence in the record that either the City or the Union made any inquiry into the number of hours spent, or reasonably required to be spent, by Leever or other canine officers on canine care when negotiating the “canine officer” provision in the CBA. In fact, the City admits that it did not know how much time Leever spent caring for Scout during her off-duty hours. Rather, when determining the amount of the salary differential for canine officers, the City relied exclusively on an asserted “comprehensive parity study,” which summarized the pay provided by other law enforcement agencies to their canine officers. The “study,” however, consisted of nothing more than handwritten notes on a desk calendar. Because no author is identified, the sources of information are not made clear, and no dates are indicated, there is nothing in the record to support that the survey was based on reliable research methods or knowledgeable and accurate sources. More importantly, the City made no showing that the canine officers employed by the agencies surveyed had hours or responsibilities comparable to Leever’s, what non-monetary benefits they received, or that their overtime compensation agreements were “reasonable” for the purpose of § 785.23.
The salary differential in Leever’s contract bears no resemblance to the compensation to which she would be entitled in overtime pay based on the number of hours she claims she actually worked. Leever claims that she spent 28 off-duty hours per week working with Scout. During the time the 1996-99 CBA was in effect, Leever’s regular wages ranged from $17.34 per hour (January 1996) to $20.51 (November 1999). Based on a 40 hour work week, Leever’s wage rate at the time she resigned, and an overtime rate of one and one-half times Leever’s regular pay rate, the $60.00 salary differential approximated one hour of overtime pay per week. 5 As the district court noted, one hour per week is “insufficient for the tasks involved” in performing the duties of a canine officer.
The City correctly points out that § 785.23 does not require it continually to keep track of the exact number of off-duty hours its canine officers spend working with their dogs each day. As courts have noted, it is the inherent indeterminacy of a canine officer’s off-duty hours and responsibilities that makes the application of § 785.23 appropriate.
See Holzapfel,
In holding that an agreement under § 785.23 must take into account some approximation of the hours actually worked, or reasonably required to be worked, by the employee, our approach is consistent with the Sixth Circuit’s approach to evaluating the reasonableness of such agreements. In
Brock v. City of Cincinnati,
CONCLUSION
Here, the district court determined that the agreement was reasonable as a matter of law solely because it was negotiated by the City and the Union at arms-length and incorporated into the CBA. Because it did not consider all of the facts and circumstances surrounding the agreement in reaching its conclusion that the agreement was reasonable under § 785.23, we reverse the grant of summary judgment in favor of the City and remand this case to the district court for further proceedings consistent with this opinion. 7
REVERSED and REMANDED.
Notes
. Courts have generally agreed that caring for and training police dogs is compensable work under the FLSA.
See, e.g., Reich v. N.Y. City Transit Auth.,
. Although we adopt the parties’ nomenclature in referring to § 785.23 as providing for an “exemption” or “exception,” we recognize that ”[r]ather than providing employers with an exception to the FLSA overtime pay requirements, § 785.23 simply offers a methodology for calculating how many hours the employees actually worked within the meaning of the FLSA.”
Brigham v. Eugene Water & Elec. Bd.,
. Leever correctly points out that even if the Union was authorized to represent her, it could not waive rights guaranteed to her under the FLSA.
See Barrentine v. Arkansas Best Freight Sys., Inc.,
. We accept the Department of Labor’s interpretive regulations of the FLSA, including § 785.23, as persuasive, although they are not binding.
See Brigham,
. We do not mean to suggest that the rate of pay for home canine care must be equal to the rate of pay for law enforcement work. We need not and do not take any position on that issue. We note that the Wage and Hour Administrator's position is that "dog care activities ... do not have to be compensated at the same rate of pay as paid for law enforcement activities.” Dep’t of Labor, Wage & Hour Div., Op. Ltr.,
. The City’s argument that it "could not have known” how many hours Leever spent working with Scout each pay period and how much of Leever's time with Scout was "truly devoted to work” is unpersuasive. Its obligation was to make an investigation as to the number of off-duty hours canine officers were reasonably required to work per pay period and to take a reasonable estimate of such hours into account in its CBA negotiations.
. For the reasons stated in our opinion, we also decline, on this record, to conclude that the agreement is unreasonable as a matter of law.
