Unlike our other edible animal favourites from M&S - Colin the Caterpillar and Percy Pig - Walter actually looks pretty lifelike.
The milk chocolate dog is priced at £5 and is part of the store's Easter range, which is sold out online but still available in stores.
Also in the same range as Walter, are his pals white-chocolate Bella Bunny and milk-chocolate Kylie Koala (both £5).
Percy Pig hasn’t been forgotten, however. M&S is selling the beloved character in hollow chocolate form. 'Giant Percy with Jazzy Sprinkled Trousers' is made from strawberry and raspberry flavoured white chocolate and can be yours for £10.
Last Easter, Marks and Spencer unveiled an Easter Bunny Colin the Caterpillar cake that consumers described as a “thing of nightmares”.
“Looks like the bunny from Donnie Darko. They should save it for Halloween, it looks demonic,” one person wrote, while another said the cake bore a resemblance to the Were-Rabbit from Wallace and Gromit.
Colin the Caterpillar celebrated his own 30th birthday in 2020.
Last year, the retailer revealed it now sells more than 450,000 Colin cakes every year and that, since Colin's launch in 1990, it has sold over seven million cakes.
Marks and Spencer said it takes 47 people to assemble each Colin cake and it uses 8.4 tonnes of sweets to decorate them each year.
