The Weimaraner (/ˈwaɪmərɑːnər/ WY-mə-rah-nər) is a large dog that was originally bred for hunting in the early 19th century. Weimaraners can have several unique physical characteristics such as small lobes on the inside of the ear, known as 'Harrasburg Horns', and 'Grafmar's Caps', very light gray patches between the ears. Raised food bowls have been found to more than double the risk of bloat in large dogs. Skin allergies are common among weimeraners. A vet should be consulted if a dog starts to lose hair, itch constantly or develop rashes. Raised food bowls have been found to more than double the risk of bloat in large dogs.
