Abstract：要旨

Behaviour problems and anxieties in dogs decrease their quality of life and may lead to relinquishment or euthanasia.

犬の行動問題や不安は生活の質を低下させ、飼育放棄や安楽死につながることもある。

Considering the large number of pet dogs and the commonness of these problematic behaviours, a better understanding of the epidemiology and related molecular and environmental factors is needed.

ペットの犬の数が多く、これらの問題行動が一般的であることを考慮すると、疫学および関連する分子的・環境的要因のより深い理解が必要である。

We have here studied the prevalence, comorbidity, and breed specificity of seven canine anxiety-like traits: noise sensitivity, fearfulness, fear of surfaces and heights, inattention/impulsivity, compulsion, separation related behaviour and aggression with an online behaviour questionnaire answered by dog owners.

私たちは、犬の飼い主が回答するオンライン行動調査票を用いて、7つの犬の不安様特徴（騒音過敏、恐怖心、表面や高所恐怖、不注意/衝動性、強迫、分離関連行動、攻撃性）の有病率、併存率、犬種特異性を調査した。

Our results show that noise sensitivity is the most common anxiety-related trait with a prevalence of 32% in 13,700 Finnish pet dogs.

その結果、騒音過敏症は最も一般的な不安関連形質であり、13,700頭のフィンランドの愛犬における有病率は32％であった。

Due to the high prevalence of noise sensitivity and fear, they were the most common comorbidities.

騒音過敏症と恐怖症の有病率が高いため、これらの合併症が最も多かった。

However, when comparing the relative risk, the largest risk ratios were seen between hyperactivity/inattention, separation related behaviour and compulsion, and between fear and aggression.

しかし、相対リスクを比較すると、多動・不注意、分離関連行動、強迫の間、恐怖と攻撃性の間で最大のリスク比が見られた。

Furthermore, dog breeds showed large differences in prevalence of all anxiety-related traits, suggesting a strong genetic contribution.

さらに、犬種はすべての不安関連形質の有病率に大きな差を示し、遺伝的な関与が強いことが示唆された。

As a result, selective breeding focusing on behaviour may reduce the prevalence of canine anxieties. Anxious animals may suffer from chronic stress and thus, modified breeding policies could improve the welfare of our companion dogs.

その結果、行動に焦点を当てた選択的繁殖が犬の不安症の蔓延を減らすかもしれない。不安症の動物は慢性的なストレスに苦しんでいる可能性があるため、繁殖方針を修正することで伴侶犬の福祉を向上させることができるだろう。

Prevalence, comorbidity, and breed differences in canine anxiety in 13,700 Finnish pet dogs - Scientific Reports

Behaviour problems and anxieties in dogs decrease their quality of life and may lead to relinquishment or euthanasia. Considering the large number of pet dogs and the commonness of these problematic behaviours, a better understanding of the epidemiology and related molecular and environmental factors is needed. We have here studied the prevalence, comorbidity, and breed specificity of seven canine anxiety-like traits: noise sensitivity, fearfulness, fear of surfaces and heights, inattention/impulsivity, compulsion, separation related behaviour and aggression with an online behaviour questionnaire answered by dog owners. Our results show that noise sensitivity is the most common anxiety-related trait with a prevalence of 32% in 13,700 Finnish pet dogs. Due to the high prevalence of noise sensitivity and fear, they were the most common comorbidities. However, when comparing the relative risk, the largest risk ratios were seen between hyperactivity/inattention, separation related behaviour and compulsion, and between fear and aggression. Furthermore, dog breeds showed large differences in prevalence of all anxiety-related traits, suggesting a strong genetic contribution. As a result, selective breeding focusing on behaviour may reduce the prevalence of canine anxieties. Anxious animals may suffer from chronic stress and thus, modified breeding policies could improve the welfare of our companion dogs.
