Dangerous Dogs in Germany: Breed Restriction Lists, Legal Situation & Facts

Der Begriff „Gefahrenhund" bezeichnet rechtlich als gefährlich eingestufte Hunde — entweder aufgrund ihrer Rasse (Rasseliste/Listenhunde) oder aufgrund konkreten Verhaltens (nachgewiesene Beißvorfälle, Aggression). Die Rechtslage in Deutschland ist Ländersache: Jedes Bundesland reguliert Haltung, Auflagen und Verbote eigenständig.

Dangerous dogs in Germany: breed restriction lists, legal situation & facts

What is a dangerous dog?

The term “dangerous dog" legally refers to dogs classified as dangerous — either because of their breed (breed restriction list/restricted breed dogs) or because of specific behavior (documented bite incidents, aggression). In Germany, the legal situation is a matter for the federal states: each state independently regulates ownership, requirements, and bans.

Two classification principles exist side by side: breed-based classification (BSL — Breed-Specific Legislation) and behavior-based classification (individual case assessment through temperament testing or bite incident documentation). Both have legal and scientific implications.

Background + scientific classification

Patronek et al. (2013, JAVMA, PubMed 24299544) analyzed 256 fatal dog bite incidents in the USA (2000–2009): in 80% of cases, at least four simultaneous risk factors were present — lack of socialization, keeping without supervision, a history of aggressive behavior, and lack of neutering. Breed was only one of many factors. The authors concluded that breed-based laws do not address the actual risk factors.

Cornelissen and Hopster (2010, Veterinary Record, PubMed 20056241) investigated dog bite incidents in the Netherlands after the introduction of BSL: breed bans did not demonstrably reduce the total number of bite incidents. The breeds most frequently involved in incidents changed — other breeds took over the role of the banned ones. Behavior-based and educational measures showed better results.

Ott et al. (2008, Journal of Veterinary Behavior, PubMed 18237517) compared Golden Retrievers with breeds affected by BSL in standardized behavior tests: no significant differences in aggressive behavior between the groups. Behavioral differences were more closely linked to ownership history and socialization than to breed.

Vitomalia position

Breed-based dangerous dog laws are not scientifically substantiated and shift the problem rather than solving it. A dog does not become dangerous because of its breed — but because of housing conditions, lack of socialization, and training history. Vitomalia supports behavior-based individual case assessment instead of blanket breed bans.

When does dangerous dog status become relevant?

  • When keeping breeds on the breed restriction list of the respective federal state
  • After a bite incident: official classification as a dangerous dog is possible
  • When applying for an ownership permit for breeds subject to listing requirements
  • When moving to another federal state: different rules may apply
  • For insurance and tenancy law questions: dangerous dog status affects both

Practical application

Breed restriction lists — overview by federal state (selection):

Federal state Category 1 (ban/strict requirements) Category 2 (with requirements)
Bavaria Pit Bull, American Staffordshire Terrier, Staffordshire Bull Terrier, Bandog Rottweiler, Doberman, among others
NRW Pit Bull, American Staffordshire, Staffordshire Bull, Tosa Inu Rottweiler, Mastiff, Mastino, among others
Berlin American Pit Bull Terrier, American Staffordshire, Staffordshire Bull, Tosa Inu
Hamburg American Pit Bull Terrier Rottweiler, American Staffordshire, among others

Lists change through legislation — always check the current regulation of the respective federal state.

Typical requirements for Category 2 dogs: - leash requirement in public spaces - muzzle requirement (in some cases) - Temperament test as a prerequisite for an ownership permit - Increased liability insurance requirement - Proof of competence for the dog owner

Common mistakes & myths

  • “Certain breeds are naturally dangerous.” Behavioral science and veterinary medicine refute breed predetermination for aggression. Ownership conditions, socialization, and training history are decisive.
  • “Breed bans protect the public.” International studies show that BSL does not reduce bite incidents. After bans, other breeds take on the role previously attributed to the banned ones.
  • “A dangerous dog is always a risk.” Many dogs on breed restriction lists pass temperament tests without issue. The classification is based on breed, not on individual behavior.

Scientific status 2026

International veterinary and behavior organizations (AVSAB, BSAVA, WSAVA) reject BSL as ineffective and disproportionate. Behavior-based assessment systems, dog owner competence requirements, and early intervention in high-risk ownership situations are considered evidence-based alternatives. Compared with other European countries, Germany remains highly fragmented — EU-wide harmonization is lacking.

Frequently asked questions

Which dogs are considered dangerous dogs in Germany?

The lists vary by federal state. Common nationwide examples: American Pit Bull Terrier, American Staffordshire Terrier, Staffordshire Bull Terrier (category 1, usually banned or strictly regulated). Category 2 with conditions: Rottweiler, Dobermann, mastiff types. Always check the current regulation of the respective federal state — lists can change.

What does dangerous dog status mean for me as a dog owner?

Permit requirement for keeping a dog, leash requirement, in some cases muzzle requirement, increased liability insurance, proof of competence. Violations can lead to fines and the removal of the animal. When moving to another federal state: check the new rules yourself.

Can a dangerous dog lose its status?

In some federal states, yes — a passed temperament test clears category 2 dogs for keeping. Category 1 bans are usually absolute. Behavior-based reassessments after documented training are possible in individual cases — depending on the federal state and the authority.
