Are Weimaraners in Nintendogs?

No. Weimaraners ("Weims") are **not available** in any version of Nintendogs (DS), Nintendogs + Cats (3DS), or the mobile Nintendogs app.

Available Breeds by Version

• Nintendogs (DS) - 6 Versions: Labrador, Golden Retriever, German Shepherd, Beagle, Corgi, Miniature Schnauzer, Toy Poodle, Chihuahua, Dachshund, Pug, Siberian Husky, Shiba Inu, Cavalier King Charles Spaniel, Shetland Sheepdog, Boxer, Dalmatian. (Varies per cartridge: Lab & Friends, Chihuahua & Friends, etc.)
• Nintendogs + Cats (3DS): Adds French Bulldog, Papillon, Welsh Corgi Pembroke, plus cats. Still no Weimaraner.

Closest In-Game Alternatives

• German Shorthaired Pointer: Similar hunting build, coat pattern (liver/white), high energy.
• Vizsla: Not in game, but visually closest real-world cousin.
• Labrador Retriever (Silver/Charcoal color): Some labs have dilute coats resembling "Silver Lab" controversy; not a Weim.

If you want a Weimaraner virtual pet, check The Sims 4 (Cats & Dogs DLC) or dedicated mobile apps like My Dog.
