delivered the Opinion of the Court.
11 The People brought an interlocutory appeal pursuant to section 16-12-102(2), C.R.S. (2011), and C.A.R. 4.1, assigning error to the district court's suppression of contraband seized from the defendant's vehicle on two separate occasions. In each case, after the defendant was arrested for driving under suspension, a police narcotics detection canine was brought to the seene and led around her truck, which had been parked and left at the location of her arrest. Also in each case, after the dog alerted to the presence of narcotics, a search of the truck's cab revealed drug paraphernalia and suspected methamphetamine. The district court found that under these circumstances, the state constitution barred the police from bringing a trained narcotics detection dog within detection range of the defendant's vehicle without first having reasonable suspicion to believe it *368contained contraband, which the court found to be lacking in both cases.
{2 We now hold that an interest in possessing contraband cannot be deemed legitimate under the state constitution any more than under the federal constitution, and that official conduct failing to compromise any legitimate interest in privacy cannot be deemed a search under the state constitution any more than under the federal constitution. Because narcotics dogs could not communicate anything more than reason to believe the defendant's truck either contained or did not contain contraband, no reasonable privacy interest was infringed upon in permitting narcotics dogs to sniff around the vehicle. The district court's order is therefore reversed, and the case is remanded for further proceedings.

13 On two occasions in 2011, what appeared to be contraband was discovered in Heather Esparza's pick-up truck by an officer of the Craig Police Department. In each instance, she was charged with possession of drug paraphernalia and possession of two grams or less of a schedule IL controlled substance. The defendant filed motions to suppress the evidence seized in each case, solely on the basis of article II, section 7 of the state constitution. Following a joint motions hearing, in which the only witnesses were four police officers involved in her arrests and the searches of her truck, the district court made findings of fact and conclusions of law.
T4 As relevant to this appeal, the court found that the defendant was lawfully stopped on the first occasion for a traffic violation, and after it was determined that her driver's license had been suspended, she was arrested for driving under suspension. On the second occasion, about two months later, she was lawfully contacted in a motel parking lot after the same officer observed her driving, and when it was confirmed that her driver's license was still suspended, she was again arrested. On each occasion, the defendant's truck was left, by request and in conformity with department policy, parked at the location of her arrest. In each case, a narcotics detection canine was brought near the exterior of her parked truck, and after the dog alerted to the presence of narcotics in the vehicle, the police entered it and found a glass pipe with a white residue, which field-tested positive for methamphetamine.
¶ 5 Relying primarily on our holding in People v. Haley, 41 P.3d 666 (Colo.2001), the district court found that under these cireum-stances, reasonable suspicion was required to subject the exterior of the defendant's vehicle to a canine sniff and in these cases the police lacked the required suspicion. The court therefore found a violation of article II, section 7 of the Colorado Constitution in each case and granted both motions to suppress. The People filed a notice of interlocutory appeal, as permitted by section 16-12-102(2), C.R.S. (2011), and C.A.R. 4.1, assigning error only to the district court's ruling that reasonable articulable suspicion was constitutionally required to bring narcotics detection dogs into sufficient proximity with the exterior of the defendant's truck to make it possible for them to detect contraband inside.

¶ 6 In Ilinois v. Caballes, 543 U.S. 405, 409, 125 S.Ct. 834, 160 L.Ed.2d 842 (2005), the United States Supreme Court held that walking a trained narcotics detection dog around a car that had not been unlawfully stopped and was not being unlawfully detained did not implicate the protections of the Fourth Amendment. The Court reasoned that official conduct not compromising any legitimate interest in privacy is not a search within the meaning of the Fourth Amendment; that no interest in possessing contraband can be deemed legitimate; and therefore that governmental conduct capable of revealing nothing more than the possession of contraband cannot be a constitutionally cognizable search. Id. Reasoning further that narcotics detection dogs can disclose only the presence or absence of contraband, the Court concluded that while a dog sniff may be the consequence of an unlawful search or seizure of the person or object subjected to a sniff, it cannot itself be the cause of a constitutional violation. Id. at 409-10, 125 S.Ct. 834.
*369T7 Shortly after the United States Supreme Court first opined that a dog sniff would not constitute a constitutionally cognizable search, see United States v. Place, 462 U.S. 696, 103 S.Ct. 2637, 77 L.Ed.2d 110 (1983), this court took issue with that determination, finding more persuasive an alternate opinion in the case analogizing dog sniffs to minimally intrusive seizures, like investigatory stops accompanied by weapons frisks. See People v. Unruh, 713 P.2d 370 (Colo.1986). In Unruh, this court took the position that state constitutional protections against unreasonable searches and seizures would therefore not require dog sniffs to be supported by probable cause and a warrant but would require them to be supported by reasonable articulable suspicion. Id. at 379. In neither Unruh nor any of the handful of other dog-sniff cases decided by this court, however, has that proposition actually controlled the outcome of a case. We have therefore had little occasion to justify or explain in detail our reasoning for this interpretation, beyond simply relying on prior constructions of the state constitution as providing greater privacy protections than the federal constitution.
¶ 8 Unlike the Supreme Court's construction of the Fourth Amendment, we have in the past interpreted our own constitution to protect as reasonable even privacy interests necessarily exposed to third-party businesses or service providers in the course of using of their commercial service. See, e.g., People v. Corr, 682 P.2d 20 (Colo.1984) (finding reasonable expectation of privacy in telephone toll records, despite that information necessarily being available to service provider); People v. Sporleder, 666 P.2d 135 (Colo.1983) (same for out-going calls monitored by pen-registers); Charnes v. DiGiacomo, 200 Colo. 94, 612 P.2d 1117 (1980) (finding reasonable expectation of privacy in bank transactions, despite their necessary disclosure to, and recording by, bank personnel). We have never suggested, however, that a privacy interest in the possession of contraband could be considered reasonable or that a drug detection dog could reveal more about the contents of a closed container than some likelihood that they do or do not include contraband. Rather, our dog sniff cases have been concerned with the nature of the particular container being pursued and any official conduct making it possible for a trained drug dog to sniff the container in the first place. In each of our prior cases, we ultimately found either that the police actually had the requisite reasonable suspicion in any event or that bringing a drug dog close to the container in question was suppressible as the consequence, or fruit, of an illegal detention. See, e.g., Haley, 41 P.3d at 677 (finding that defendant's vehicle was unlawfully detained when dog sniff occurred); People v. Reyes, 956 P.2d 1254 (Colo.1998) (finding reasonable suspicion for dog sniff of vehicle's exterior); People v. May, 886 P.2d 280 (Colo.1994) (finding reasonable suspicion for dog sniff of express mail package held by postal workers); People v. Boylan, 854 P.2d 807, 812 (Colo.1993) (finding reasonable suspicion for dog sniff of package detained by Federal Express workers); People v. Wieser, 796 P.2d 982, 987 (Colo.1990) (Mullarkey, J., concurring in the judgment) (producing majority for reversal by finding existence of reasonable suspicion prior to dog sniff of storage locker); Unruh, 713 P.2d at 377-78 (finding reasonable suspicion for dog sniff of burglarized safe).
T 9 Despite our broad language purporting to address dog sniffs in general, all of our cases have therefore actually involved some admixture of considerations implying a more limited rule. In Reyes, by expressly reserving the question "whether a canine sniff of an automobile's exterior constitutes a 'search' that must be supported by a reasonable suspicion that the vehicle contains evidence of a crime," we clearly rejected the broad proposition that a dog sniff of any closed container would, in and of itself, constitute a constitutionally cognizable search. 956 P.2d at 1256 n.1. Similarly in Haley, we declined to affirm suppression on the basis of an absence of reasonable articulable suspicion for a dog sniff alone. 41 P.3d at 676. Instead, we excluded consideration of a drug dog's alert from the calculus of probable cause to support a search of the defendant's vehicle only because the dog sniff was made possible by, and was therefore the product or fruit of, an unlawfully prolonged detention of the defen*370dant's vehicle Id. at 672 n. 4 (relying on People v. Redinger, 906 P.2d 81, 85-86 (Colo.1995) for requirement of reasonable suspicion to prolong any traffic stop beyond its original purpose); cf. Caballes, 543 U.S. at 407-10, 125 S.Ct. 834 (accepting that a dog sniff could be suppressed as the product of an unlawfully prolonged vehicle detention but finding none in that case).
¶ 10 In the instant interlocutory appeal by the People there is no suggestion that the defendant's truck was unlawfully stopped or detained or any challenge to the court's finding that the police lacked reasonable suspicion to believe the truck contained contraband. Nor is there any suggestion that under the circumstances of these cases the police were unable to approach the exterior of the truck after the defendant's arrest and removal without violating a reasonable privacy interest. Cf. Wieser, 796 P.2d 982 (Mullarkey, J., concurring in the judgment) (finding reasonable expectation of privacy in broader fenced-in storage facility containing defendant's individual storage locker that was subjected to dog sniff). The district court simply found that despite the defendant's lawful arrest and the fact that her truck was left, at 'her request, parked in a public place, she nevertheless retained a privacy expectation in her vehicle requiring reasonable suspicion for a dog sniff, In light of the history of dog sniff cases in this jurisdiction since Unruh, the further development of Fourth Amendment law concerning dog sniffs and other sensory enhancing technology, and the outcome-determinative nature of the district court's rationale, we consider it both appropriate and necessary to narrow our own pronouncements concerning the use of trained narcotics detection dogs. '
T11 Neither of the premises of the Supreme Court's Caballes rationale falls within our state constitutional exception for disclosure of private matters to commercial third parties, nor can we find differences in the language or history of article II, section 7 disputing either premise. We therefore decline to find that article II, section 7 protects any privacy interest in the possession of contraband or, as a factual and conceptual matter, that the alert of a trained narcotics detection dog can indicate anything more than the presence or absence of contraband. To the extent that we had previously suggested otherwise, we now reject the broad proposition that government conduct permitting a trained narcotics detection dog to sniff outside a closed container, in and of itself, infringes upon reasonable privacy interests in the contents of that container, thereby constituting a search within the meaning of article II, section 7.
112 Whether a particular dog sniff is a consequence of an earlier illegality so as to require its suppression as a fruit of that illegality necessarily depends upon the facts and circumstances of each case. Similarly, whether the location or conduct of particular dog sniffs may infringe on a liberty interest so as to constitute a seizure are matters not foreclosed by our holding today. Cf. Jardines v. Florida, 73 So.3d 34 (Fla.2011), cert. granted in part, - U.S. -, 132 S.Ct. 995, 181 L.Ed.2d 726 (2012) (noting that dog sniff conducted at private residence may also expose resident to public opprobrium, humiliation, and embarrassment). Finally, although both this court and the Supreme Court have recognized that dog sniffs may be sufficiently reliable to supply probable cause for a search, that determination necessarily rests on the foundational evidence produced in each case. No more than the federal constitution, however, does the state constitution preclude the detection of contraband in someone's possession by trained narcotics detection dogs, regardless of the reasonableness of his expectation of privacy in the area or container outside of which a dog sniff is conducted.
III.
T13 In this case, the district court unre-markably found that the defendant maintained a privacy expectation in her vehicle, even while it was left parked in a public place. Relying on broad language from our prior dog sniff cases, it therefore concluded that commencing canine sniffs of the exterior of the defendant's vehicle without reasonable suspicion of illegal drugs was prohibited by the state constitution. In light of the Su*371preme Court's holding in Caballes, permitting a suspicionless dog sniff of a lawfully detained vehicle, and our own reconciliation of the federal and state constitutional provisions governing dog sniffs, the district court's suppression order no longer finds support in the provisions of the state constitution.
IV.
1 14 Because the dog sniffs of the defendant's vehicle in these cases were neither a search cognizable under article II, section 7 of the Colorado Constitution nor the fruit of an unlawful search or seizure, the district court's suppression order is reversed, and the case is remanded for further proceedings.
