Judging by the astronomical sales figures that Nintendogs has racked up in Japan, Shigeru Miyamoto's Tamagotchi-style puppy simulator must be the mutt's nuts.
And Nintendo has thrown US doggers a bone by announcing that when the game gets let off the lead on August 22 there'll be three new breeds to play with: the Boxer, the Golden Retriever, and the Siberian Husky.
Nintendo hasn't confirmed that the European version of Nintendogs, due in November, will also contain these breeds. We could even get all new breeds like the classic British Bulldog and that proud Northern favourite, the Scabby Mongrel ( with a piece of string for a lead, we hope - Ed).
The US version will be available in three different versions, each containing six different breeds. The Miniature Dachshund and Friends edition will include Beagles, Pugs, Shih Tzus, and the new Golden Retriever and Siberian Husky breeds.
The Chihuahua and Friends edition will feature the new Boxer, German Shepherds, King Charles Spaniels, Shetland Sheepdogs, Yorkshire terriers and the posh rat-mutts of the title.
And the Labrador Retriever and Friends edition will remain as it was in Japan: Labs, Miniature Schnauzers, Toy Poodles, Pembroke Welsh Corgis and Shiba Inus.
Nintendogs lets you train your sickeningly cute little puppy into an even more sickeningly cute little puppy. The DS's microphone lets you teach your mutt voice commands and the wireless link lets your puppy sniff the ass of other player's dogs in multiplayer.
