In Modoc County, regulations concerning loose dogs are stringent, with both the City of Alturas and the county enforcing strict rules to ensure responsible pet ownership. Dogs found off their owner’s property without a leash or proper control are classified as “at large,” leading to potential fines and impoundment.
In Alturas, dogs must be confined or leashed unless engaged in approved activities, such as police work or sanctioned events. Owners are accountable for their pets’ waste, noise control, and preventing property damage or harassment. Dogs that repeatedly roam free or are left unattended while in heat may be deemed a nuisance or dangerous, resulting in fines and possible restrictions on ownership.
The county enforces similar standards. Dogs roaming without supervision face impoundment, while those used for herding or hunting are exempt during their work. Unlicensed or unvaccinated dogs found at large can be taken by animal control, and if unclaimed within a few days, they may be rehomed or euthanized. Owners must pay fines and provide proof of vaccinations to reclaim their pets. Additionally, abandoning animals is illegal, punishable by fines or jail time.
Both jurisdictions define criteria for “potentially dangerous” or “vicious” dogs, including unprovoked bites or repeated attacks on other animals. Such dogs must be confined, licensed with special designations, and may require insurance. In extreme cases, destruction of the animal may be mandated, with avenues for owners to appeal decisions.
Alturas limits pet ownership to four dogs and six cats over six months unless a kennel or rescue license is obtained. All dogs over four months must be vaccinated against rabies and licensed annually, with tags required at all times. Noncompliance can lead to escalating penalties.
Responsible pet ownership in Modoc County is legally mandated, emphasizing the importance of leashing dogs, licensing, and ensuring they do not pose a threat to others. For further details, residents can reach out to the Modoc County Sheriff’s Office or Alturas City Hall.
