The Weimaraner[a] is a German breed of hunting dog of medium to large size, with history going back at least to the nineteenth century.

[3] Many theories of the origin of the Weimaraner have been advanced, but there are few documented historical facts; silver-grey dogs are shown in paintings by Antoon van Dyck in the seventeenth century and by Jean-Baptiste Oudry in the eighteenth.

[5]: 545 [6][c] In the early years of the twentieth century – the time of the Great War – the Weimaraner came close to extinction; it was reconstituted from the few surviving examples of the breed.

[1] The coat may be mouse-grey, roe-grey or silver-grey in various shades, or of a colour intermediate between these; minor white markings to the feet and chest are tolerated.

[11]: 6  Other diseases or defects to which it has some genetic or statistical predisposition include corneal dystrophy, distichiasis, entropion, eversion of the cartilage of the nictitating membrane, generalised demodicosis, medial canthal pocket syndrome, refractory corneal ulceration and XX sex reversal,[12]: 153  and also – in dogs only – Weimaraner neutrophil dysfunction,[13]: 928  pododermatitis and tricuspid dysplasia.
