The conditions the breed clubs and health schemes name for the アメリカンスタッフォードシャーテリア. Most animals of the breed never get them; this is what to ask a breeder or an insurer about.
An inherited adult-onset brain disease that causes loss of balance and coordination; a DNA test is available and recommended for breeding dogs. OFA/CHIC lists the NCL-A DNA test for the American Staffordshire Terrier ↗
Joint malformations that can lead to lameness and arthritis; breeding dogs should be hip and elbow scored. Wikipedia cites a North American study with 24.4% hip and 16.1% elbow dysplasia; OFA/CHIC requires hip and elbow evaluations ↗
The breed is prone to itchy allergic skin and to demodectic mange. Named as breed predispositions on Wikipedia (vet literature) ↗
Not veterinary advice: for your own animal, ask your vet.
Running costs for a アメリカンスタッフォードシャーテリア, built from current prices in each country: food scaled to the weight of the breed, insurance to its size, the rest per country. The purchase price and unplanned vet bills come on top.
Estimates from the sources linked on each line. Food: a complete dry food at about 3,600 kcal/kg at the NRC maintenance energy for the average weight of the breed. Insurance: a typical adult policy scaled by size; real quotes depend on breed, age and cover.

この犬種は元々ブル・アンド・テリア・ドッグと呼ばれ、その後イングランドのスタッフォードシャーにちなんでスタッフォードシャー・ブル・テリアとなりました。アメリカに渡るとスタッフォードシャー・テリアと呼ばれ、後にアメリカン・スタッフォードシャー・テリアに改名されました。8
大きな伸びをしてしっぽを振りながら目覚め、一日の準備は万端。飼い主と一緒にさっさと散歩に出かけ、郵便屋さん、隣の猫（遠くからだけど）、通りの小さな犬など、友達全員に挨拶するんだ。私は強くて自信満々だけど、すごく甘えん坊でもある。家では綱引きや取ってこい遊びが大好きだけど、一番のお気に入りはソファで寄り添うこと。家を見張って警戒心は強いけど、飼い主が近くにいる時が一番幸せ。夜はベッドの足元で丸くなり、安全で愛されていると感じながら、明日の冒険の夢を見るんだ。
お遊びの創作話です。アドバイスではありません。
ブル・アンド・テリア犬は1850年頃にアメリカに渡り、農場犬や万能犬として使われました。AKCは1936年にスタッフォードシャー・テリアとして登録し、1969年に「アメリカン」を追加して、より小型のイギリスのスタッフォードシャー・ブル・テリアと区別しました。21
