Following a jury trial, Christopher Pless appeals his conviction on three counts of violating county animal control ordinances (two counts of failing to restrain his pit bull dogs and one count of allowing his dogs to become a public nuisance). He challenges the sufficiency of the evidence, questions the constitutionality of the county ordinance, and argues that the trial court erred in its rulings on evidence and on sentencing and further erred in finding he received effective assistance of counsel. For the reasons set forth below, we affirm in part and reverse in part.
*7991. When reviewing a defendant’s challenge to the sufficiency of the evidence, we view the evidence in the light most favorable to the jury’s verdict, and the defendant no longer enjoys the presumption of innocence. Short v. State1 We do not weigh the evidence or determine witness credibility, but only determine if the evidence was sufficient for a rational trier of fact to find the defendant guilty of the charged offense beyond a reasonable doubt. Jackson v. Virginia. 2
So construed, the evidence shows that in February 2004, in April 2004, and on several other occasions in this time frame, one or more of Pless’s five pit bull dogs were running unrestrained and loose in neighbors’ yards and garages. They frightened children and adults and barked aggressively. In addition to these repeated events, on July 14, 2004, two of these dogs ran unrestrained onto a neighbor’s property, acting aggressively and not allowing the neighbor to exit her porch. Furthermore, on August 1, 2004, two of these dogs ran unrestrained onto that same neighbor’s property, chasing and frightening the neighbor’s horses. Witnesses testified that to their knowledge, on none of these occasions had any outsider gone onto Pless’s property and set the animals free.
Pless was charged with twice violating Henry County Ordinance § 3-4-7 (2), in that he failed to keep his dogs under restraint, with one incident specified on July 14 and the other on August 1, 2004. He was further charged with violating Henry County Ordinance § 3-4-7 (5), in that he allowed his dogs to become a public nuisance (as defined in Henry County Ordinance § 3-4-2). At trial, he claimed that his dogs were always kept under restraint (specifically on July 14 and August 1), and that, to the extent the dogs had ever been unrestrained, someone must have come onto his property and set them free.
The jury found him guilty on all counts, and the court sentenced him to one day in prison and 179 days of probation, with a $250 fine on each count and an order to reimburse the county $1,226 for his court-appointed attorney fees. Pless moved for a new trial, asserting among other things ineffective assistance of counsel. Finding after a hearing that Pless received effective assistance from his counsel, the court denied the motion for new trial, giving rise to this appeal.
The evidence sufficed to sustain the convictions. Henry County Ordinance § 3-4-7 (2) makes it unlawful for an owner to “[f]ail to keep an animal under restraint.” An animal is under restraint only if it is (a) secured by a leash or lead with a collar, (b) enclosed by way of a fence or other enclosure, or (c) under the supervision of a responsible and competent person at least 16 years old and obedient to the *800person’s commands, or (d) if a dog is being trained or hunted in conformance with the game laws of Georgia. Henry County Ordinance § 3-4-2. Witnesses testified that on July 14 and August 1,2004, two of Pless’s dogs were running loose in a neighbor’s yard, thus sustaining Pless’s conviction on the two charges of violating Henry County Ordinance § 3-4-7 (2).
Henry County Ordinance § 3-4-7 (5) makes it unlawful for an owner to “[a]llow any animal to become a public nuisance.” “Public nuisance” is defined, among other things, as any animal which “[i]s found repeatedly at large.” Henry County Ordinance § 3-4-2. Here, evidence showed that in the months prior to the July 14 and August 1 incidents, Pless’s dogs were repeatedly found loose in neighbors’ yards and garages. Accordingly, evidence supported the conviction on the charge of allowing an animal to become a public nuisance under § 3-4-7 (5).
2. Pless contends that Henry County Ordinance § 3-4-7 (5) regarding allowing an animal to become a public nuisance is unconstitutionally vague. However, Pless did not raise this issue in the trial court below. Because “the issue of the statute’s constitutionality was not raised below or ruled on by the trial court, ... it cannot be considered on appeal.” Davis v. State.3 See In re L. C.4 5(appellate court “ ‘will not rule on a challenge to the constitutionality of a statute unless the issue has been raised and ruled on in the trial court’ ”).
Setting aside that Pless’s enumeration of error does not address the following matter, we note that Pless further contends that the indictment failed to specify in what manner his dog was a public nuisance. If Pless wanted greater specificity with regard to the crime that he allegedly committed, his appropriate remedy was a pre-trial special demurrer. Lowe v. State.5 Raising the issue for the first time on appeal is too late. Croft v. State.6
3. Pless argues that the court erred in admitting a similar transaction from April 2004, in which Pless was charged with failing to keep his pit bull dogs under restraint. Citing Hoffer v. State7 Pless contends that such similar transaction evidence was not relevant to show intent since the relevant Henry County ordinances were strict liability crimes, which required no showing of intent.
The complained-of evidence came from the same neighbor, who testified that on April 22, 2004, several of Pless’s pit bull dogs were running unrestrained on her yard that day, leading her to call animal *801control. The responding animal control officer testified that he found one of the dogs unrestrained and accordingly issued Pless a citation.
Pless’s characterization of this incident solely as a similar transaction ignores that this evidence helped establish that he allowed his dogs to become a public nuisance by repeatedly being found at large. Proof of such “at large” incidents that took place within the two years prior to the November 2004 accusation filed against Pless were relevant to show the charge of allowing the dogs to become a public nuisance. See Green v. State8 (“ ‘evidence of guilt. . . may extend to any day previous to the [accusation] and within the statute of limitation for the prosecution of the offense’ ”). See also OCGA § 17-3-1 (d) (two-year statute of limitation for misdemeanors). Whether this evidence also constituted a similar transaction showing bent of mind or course of conduct relating to the July 14 and August 1 “failure to restrain” charges does not diminish its admissibility as proof of the “public nuisance” charge.
Furthermore, the evidence was certainly admissible as a prior difficulty between Pless and his neighbor. As stated in Appling v. State:9
Unlike similar transactions, prior difficulties between the parties are not independent acts or occurrences, but are connected acts or occurrences arising from the relationship between the same people involved in the prosecution and are related and connected by such nexus. Evidence of a defendant’s prior act toward the same victim ... is admissible as evidence of the relationship between the victim and the defendant and may show the defendant’s motive, intent, and bent of mind in committing the act against the victim which results in the charges for which the defendant is being prosecuted.
Finally, even in strict liability cases, prior similar acts may be admissible to show course of conduct or bent of mind. Putman v. State.10 We conclude that the trial court did not abuse its discretion in admitting this evidence. See Brooks v. State* 11 (applying an “abuse of discretion” standard to admission of similar transaction evidence).
4. Pless contends that the trial court erred in excluding evidence of prior difficulties between Pless and his neighbors, which evidence was supposedly found in police reports. Specifically, Pless claims he *802should have been allowed to introduce various police reports showing he had called police to investigate his complaints that unidentified persons had trespassed on his property over a period of time, during which trespasses they took pictures, opened doors, killed animals, and let animals loose.
Pless’s argument fails for the simple reason that police reports showing prior incidents are generally, by themselves, inadmissible hearsay with no probative value. Fernandez v. Ga. Theatre Co. II.12 The narrative portions of such reports, which is what Pless sought to introduce here, are “not facts that should properly be admitted under the business records exception to the hearsay rule.” Brown v. State.13 Moreover, Pless was unable to identify any of his alleged persecutors from these prior incidents, which incidents were therefore irrelevant in proving prior difficulties with his neighbors. Finally, Pless testified at length to all of these incidents at trial, and thus the police reports would have been cumulative in any case. The trial court did not abuse its discretion in excluding the reports. See Watson v. State14 (applying “abuse of discretion” standard to decision to exclude evidence).
5. Pless claims that the trial court erred in denying his motion for new trial, in which he asserted he received ineffective assistance of counsel. He urges that his trial counsel erred in failing to (i) subpoena the officers who wrote the police reports discussed in Division 4, (ii) call Pless’s wife as a witness to the incidents reported in the police reports, and (iii) file a special demurrer to the indictment.
To prevail on his claim before the trial court, Pless bore the burden of showing both that his counsel’s performance was deficient and that the deficient performance was prejudicial to his defense. See Strickland v. Washington.15 As evidence supported the trial court’s finding that Pless failed to bear this burden on any of the allegations of deficient performance, the trial court did not clearly err in denying his claim of ineffective assistance. See Morris v. State16 (applying “clearly erroneous” standard to trial court’s findings on ineffective assistance of counsel).
(a) Failure to subpoena officers. Pless first argues that his trial counsel failed to subpoena the officers who authored the police reports regarding his complaints about troubles with unidentified strangers at his property. As discussed in Division 4 above, these police reports were inadmissible hearsay and were irrelevant in any case. Pless’s trial counsel testified that based on his interviews with *803the officers, he concluded that they did not remember anything helpful regarding the incidents and that they witnessed nothing firsthand. Moreover, Pless was able to testify to the incidents. Therefore, trial counsel decided as a matter of trial strategy not to subpoena the officers. Strategic decisions not to call certain witnesses, made after thorough investigation, are virtually unchallengeable and do not constitute deficient performance. Johnson v. State.17
(b) Failure to call Pless’s wife. Similarly, Pless’s trial counsel testified that based on his interview of Pless’s wife regarding her memory of the various incidents, he did not call her as a witness because her testimony was not needed, was not relevant, and was not in his client’s best interest. Thus, the trial court could also discount this allegation as a ground for ineffective assistance of counsel.
(c) Failure to file a special demurrer. Finally, Pless claims that his trial counsel erred in failing to specially demur to the accusation, which accusation did not specify the precise method in which Pless allowed his dog to become a public nuisance. Because the State could have simply recharged Pless in a later more specific accusation, “the failure to file a special demurrer... would not support a finding of the violation of the constitutional right to effective legal representation. Wallace v. State.”18 Cotton v. State.19
6. Pless challenges his sentence on two grounds. First, arguing that the same facts proved each, he claims that the court should have merged the three charges into one charge. Second, he claims that the court failed to make the findings of fact required before ordering him to reimburse the county for his court-appointed attorney fees.
The trial court is not required to merge counts that are for sequential crimes. Cutter v. State 20 Where the evidence shows that one crime was complete before the other occurred, the crimes do not factually merge. Reeves v. State 21 Here, the “public nuisance” crime, shown by Pless’s dogs being repeatedly found at large, was complete based on the various incidents that occurred prior to the July 14 and August 1 “failure to restrain” crimes. Thus, no merger was required. Taking place over a period of several months and separated by weeks, these incidents and crimes did not necessarily constitute a single or continuing course of conduct that could only be punished as one offense. Compare McKee v. State22 (failure to obtain medical care *804for a child over a period of four consecutive days constituted a single course of conduct spanning four days, not a separate offense for each day; merger required).
Regarding the court’s requirement that Pless reimburse the county the fees incurred in paying for his court-appointed attorney (or to do community service instead), we note that Pless represented to the court that he had sufficient means to pay this amount. Nevertheless, we must reverse the imposition of these fees on the ground that the governing statute was struck prior to trial and its replacement does not contain any provisions authorizing a trial court to order a defendant to reimburse his court-appointed attorney fees. Former OCGA § 17-12-10 (c), which authorized a trial court to order reimbursement under certain circumstances (see Fowler v. State23), was struck by the Georgia Indigent Defense Act of 2003, effective on December 31, 2003. Ga. L. 2003, p. 191, § 1. Because the new statute contains no provision authorizing such reimbursement, the trial court lacked the authority to do so when it tried and sentenced Pless in May 2005 for crimes committed in 2004.24 Accordingly, we must reverse that portion of the sentence requiring Pless to reimburse the county $1,226 in attorney fees. The remainder of the sentence is affirmed.

The same 2003 Act also struck a related provision (former OCGA§ 17-12-40), which had authorized counties to recover such ordered payments. Ga. L. 2003, p. 191, § 1. Although this provision was not struck until January 1,2005 (and thus was in effect at the time of the crimes), this provision did not purport to authorize a court to order such payments in a sentence. Even if this provision could be seen as authority for such, it still would not help the State here. A defendant is sentenced according to the sentencing law in effect at the time he committed his crimes (see Lockhart v. State, 227 Ga. App. 481, 483 (489 SE2d 594) (1997)), but new sentencing provisions that pertain to procedural rights may apply ex post facto. Cannon v. State, 246 Ga. 754, 755 (1) (272 SE2d 709) (1980). Inasmuch as this provision pertained to the administrative matter of government recovery of funds expended for indigent criminal defense, such is clearly procedural; thus, the new statute, which struck this provision, applied at Pless’s May 2005 sentencing.
