Maryland Pet Laws

This page summarizes the main state laws that affect dog and cat owners in Maryland, with links to the full guide for each topic. State law sets the baseline; your city or county can add stricter rules, so check local ordinances too.

Maryland Dog License Requirements

Maryland requires dog licensing through its counties and Baltimore City: dogs at least 6 months old must be licensed under the county provisions of the Local Government Article (for example 13-112). Deadlines, fees and renewal cycles vary by county; in Anne Arundel and Montgomery the license expires with the rabies certificate.

Maryland Leash Laws

Maryland has no statewide leash law. Each county and Baltimore City sets leash and at-large rules; Charles County, for example, may ban dogs running at large with a fine of up to $25. Several counties restrict females in heat. Maryland's bite law makes owners strictly liable when a dog running at large causes injury.

Maryland Dog Bite Laws

Maryland uses a hybrid rule (Courts & Judicial Proceedings 3-1901). Evidence that a dog caused injury creates a rebuttable presumption that the owner knew it was dangerous, and an owner is strictly liable if the dog was running at large, unless the victim was trespassing, committing a crime or provoking the dog. The deadline is 3 years.

Maryland Rabies Vaccination Laws for Dogs and Cats

Maryland requires dogs, cats and ferrets 4 months or older to be vaccinated against rabies by a licensed veterinarian (Health-General 18-318). Counties enforce the rule, and some tie the dog license to the rabies certificate so the license expires when the vaccination does.

Maryland Pet Limit Laws: How Many Pets Can You Own?

Maryland has no statewide limit on household pets. A state kennel license rule applies in every county: anyone keeping 6 or more unspayed females over 6 months for breeding and sale, or selling dogs from 6 or more litters a year, needs a kennel license (LG 13-108). Counties can be stricter.
