Maryland takes dog tethering seriously, and the rules go well beyond simply telling you not to leave a dog on a chain indefinitely. The state regulates outdoor tethering at the state level under Criminal Law §10-623, and the rules are stricter than many owners realize. Whether you are a longtime dog owner or new to the state, understanding exactly what the law requires — and what it prohibits — can protect both your dog and your record.
The statute covers everything from the type of collar you may use to the weather conditions under which tethering becomes illegal. The law also makes clear that local governments may adopt requirements for the health and safety of dogs that are more stringent than the state requirements. That means county and municipal rules can — and often do — go further than the statewide baseline.

Is It Legal to Chain a Dog in Maryland?
Tethering a dog in Maryland is not outright banned, but it is heavily regulated. Under §10-623, a person may not leave a dog outside and unattended by use of a restraint that unreasonably limits the movement of the dog, that uses a collar made primarily of metal or one that is not at least as large as the circumference of the dog’s neck plus one inch, or that restricts the dog’s access to suitable and sufficient clean water or appropriate shelter.
Under the statute, a “restraint” means a chain, rope, tether, leash, cable, or other device that attaches a dog to a stationary object or trolley system. So the law applies regardless of whether you use a traditional metal chain or a nylon cable — the material does not create an exemption.
There are also specific categories of dogs that may not be tethered at all. It is illegal to tether a dog that is sick or injured. If your dog is recovering from surgery or showing signs of illness, keeping it restrained outdoors and unattended is a violation regardless of how short the duration is.

Key Insight: As of 2026, about 23 states have laws that limit or otherwise control how owners can tether their dogs. Maryland is among the more restrictive, combining a statewide statute with county-level ordinances that often add further requirements.
Time Limits on Tethering in Maryland
One of the most important — and most frequently misunderstood — aspects of Maryland’s tethering law is the time limit. Maryland law dictates that a dog may not be tethered for more than two hours in a 24-hour period, and the tether must be at least 10 feet long and allow the dog to access food, water, and shelter.
The state statute also sets a separate threshold tied to shelter access. Under §10-623(c), a person may not leave a dog outside and unattended for longer than 30 minutes without access to continuous suitable shelter during extreme weather conditions. In other words, even during mild weather, the two-hour tethering cap applies, and during extreme weather, the dog must have shelter access if it is outside at all.
Some counties apply even tighter restrictions. In Prince George’s County, for example, it is unlawful for a person to use a chain, rope, tether, leash, cable, or other device to attach a dog to a stationary object or trolley system, with an exception only for temporary restraining not to exceed one hour, during a lawful animal event, or when the owner remains with the dog throughout the period of restraint.
Frederick County sets its own limit as well. Under Frederick County’s ordinance, it is unlawful for any person to tether a dog to any stationary or inanimate object for the purpose of confinement for more than four hours, cumulatively in any 24-hour period.

Tether Length, Weight, and Equipment Requirements in Maryland
Maryland’s statewide law sets a clear floor for tether length. The tether must be at least 10 feet long and allow the dog to access food, water, and shelter. The law also governs the type of collar used: a “collar” under the statute means a device constructed of nylon, leather, or similar material specifically designed to be used around the neck of a dog. Metal collars — including choke chains — do not meet this definition and are therefore prohibited for use during tethering.
The collar must also fit properly. The collar used during tethering must not be made primarily of metal and must be at least as large as the circumference of the dog’s neck plus one inch. A collar that is too tight is a violation of the statute on its own, separate from any other tethering concern.
Some Maryland counties go further on equipment standards. In Frederick County, the dog must be tethered by a non-choke type collar or a body harness to a tether that is at least four times the body length of the dog measured from nose to hindquarters, or a minimum of ten feet, and the tether must be free from entanglement and have swivels at both ends.
Carroll County adds similar detail: the tether must have swivels at both ends to prevent kinking and knotting, and the area must be maintained so that the tether cannot become entangled and positioned so that the dog cannot wrap the tether around posts, trees, or debris, or hang by jumping a fence or guardrail.
Cecil County’s ordinance specifies that a tether to confine a dog must be a minimum of 4.5 times the length of the dog from nose to tail base, and under no circumstances less than 10 feet long, unless impossible due to property size, in which case the Animal Care and Control Authority may set forth reasonable substitute requirements.
| Jurisdiction | Minimum Tether Length | Collar Requirement | Swivels Required |
|---|---|---|---|
| Maryland (Statewide) | 10 feet | Nylon/leather; not metal; neck + 1 inch | Not specified |
| Frederick County | 4x body length or 10 feet minimum | Non-choke collar or body harness | Yes, both ends |
| Cecil County | 4.5x body length or 10 feet minimum | Follows state standard | Not specified |
| Carroll County | Follows state standard | Follows state standard | Yes, both ends |
Weather and Temperature Restrictions on Tethering in Maryland
Maryland’s weather restrictions on tethering are among the clearest provisions in the statute. Under the law, “extreme weather conditions” means temperatures below 32 degrees Fahrenheit or conditions during an active winter or cold weather warning or advisory issued by the National Weather Service. Tethering a dog during these conditions is prohibited.
The shelter requirement also activates well before extreme weather arrives. A tethered dog must have access to suitable shelter, meaning a ventilated structure with a solid floor, a weatherproof roof, and an enclosure that keeps the dog reasonably dry and at a normal body temperature, and the dog also needs suitable shade that fully covers it from direct sun.
Under the statute, “suitable shade” means an area completely protected from the direct sun that is accessible and fully covers a dog. A partial shadow from a fence post or a small awning that only covers part of the dog’s body would not satisfy this requirement.
These weather rules mean that even a brief tethering session during a cold snap or a National Weather Service advisory is a violation. You do not need to be outside for hours — the restriction applies the moment those conditions are present. If you are unsure how Maryland’s cold-weather rules compare to those in nearby states, our guide on dog chaining laws in Washington offers a useful point of comparison.
Pro Tip: Monitor the National Weather Service forecast for your county before leaving your dog outside. An active winter advisory — even a brief one — triggers Maryland’s tethering ban regardless of the actual thermometer reading at your location.
Local and Municipal Tethering Laws in Maryland
Because Maryland’s statewide law explicitly permits counties to enact stricter rules, local ordinances vary considerably across the state. Knowing your county’s rules is just as important as knowing the state baseline.
Prince George’s County has one of the most restrictive approaches. It is unlawful for a person to use a chain, rope, tether, leash, cable, or other device to attach a dog to a stationary object or trolley system, with an exception for temporary restraining for a reasonable amount of time not to exceed one hour. This is significantly shorter than the statewide two-hour limit.
Frederick County caps tethering at four cumulative hours per 24-hour period and requires specific equipment. An individual found chaining or tethering an animal in violation of Frederick County’s ordinance has 30 days to provide other means of confinement, as long as other conditions of confinement and care are being met. The grace period is null and void immediately if the owner is not in compliance with other applicable animal laws, and individuals who do not comply within the 30-day window are subject to fines and penalties.
Cecil County allows tethering for up to 12 hours within a 24-hour period under most circumstances. The owner of a dog may not tie, chain, cable, or in any way tether a dog outside for more than 12 hours within a 24-hour period, except at sporting events, unless there is inclement weather. Cecil County also lists specific exemptions, including actively herding, shepherding, or cultivating agricultural products where tethering is reasonably necessary for the dog’s safety, and during training, exhibition, performance, or sporting events where tethering does not occur for a period exceeding seven days.
Baltimore County adds its own layer of restrictions. Baltimore County requires all dogs and cats to be on a leash when off the owner’s property and prohibits the use of chain collars except during training.
Montgomery County operates under its own tethering regulation, adopted under Section 5-201(b) of the Montgomery County Code and interpreted alongside Maryland’s state anti-cruelty provisions at Criminal Law §10-604(a). Under Montgomery County’s rules, the particular circumstances or conditions of a dog otherwise tethered according to the requirements of the regulation can still be sufficient evidence of cruelty to constitute a violation of state or county law.
- Prince George’s County: Tethering effectively prohibited; exception for up to one hour of temporary restraint
- Frederick County: Maximum four cumulative hours per 24-hour period; 30-day grace period for first violations
- Cecil County: Maximum 12 hours per 24-hour period; sporting event exemption applies
- Baltimore County: Chain collars banned except during training; leash required off property
- Montgomery County: Circumstances can constitute cruelty even when technical requirements are met

Penalties for Violating Dog Chaining Laws in Maryland
Maryland does not treat tethering violations lightly. Violating the tethering statute is a misdemeanor, and a conviction can bring up to 90 days in jail, a fine up to $1,000, or both — making this one of the more heavily penalized routine dog ownership violations in the state.
The misdemeanor classification means a tethering conviction becomes part of your criminal record, not just a civil citation. This is a meaningful distinction that separates Maryland from states that treat tethering violations as simple infractions with small fines. If you are charged under §10-623, you have the right to contest the charge in court.
At the county level, penalties vary. Cecil County sets fines of up to $500 for violations of its animal care standards. In Frederick County, a person found in violation has 30 days to provide other means of confinement as long as other care conditions are met, but the grace period is null and void immediately if the owner is not in compliance with other applicable animal laws, and those who do not comply within 30 days are subject to the fines and penalties stipulated in that chapter.
Animal control officers across the state have authority to investigate tethering complaints and issue citations. If a situation rises to the level of animal cruelty under Maryland Criminal Law §10-604, the penalties become significantly more severe than those under §10-623 alone.
| Jurisdiction | Violation Type | Maximum Penalty |
|---|---|---|
| Maryland (Statewide §10-623) | Misdemeanor | 90 days imprisonment and/or $1,000 fine |
| Cecil County | Civil/animal care violation | Up to $500 |
| Frederick County | Ordinance violation | 30-day cure period, then fines per chapter |
| Baltimore County (leash/collar) | Civil violation | $100 (unlicensed pet); separate leash penalties |
If you want to see how penalty structures differ across the region, our guides on dog chaining laws in Indiana, dog chaining laws in Missouri, and dog chaining laws in Texas offer useful comparisons. Maryland dog owners may also want to review related state-specific rules such as backyard chicken laws in Maryland and roadkill laws in Maryland to stay fully informed about animal-related regulations in the state.
The bottom line is straightforward: if you own a dog in Maryland, tethering it outdoors requires careful attention to duration, equipment, weather conditions, and your specific county’s rules. The statewide law under Maryland Criminal Law §10-623 sets the minimum standard, and local ordinances frequently raise that bar further. When in doubt, contact your county’s animal control office directly — they can tell you exactly what applies in your area and help you avoid a misdemeanor charge that carries real consequences.
