Awww cheer up Double head! They can call you 'Uncle Double head'. The other silent hill dogs won't think you've gone soft. Not at all. I'm sure of it. Feral and Sniffer dog totally won't make fun of you.
When Mira and Smile dog go out Mira asks Double head to look after the pups, and he does 'cause he's a good friend. And of course he ends up with chew marks.
And notice the pups in the front have identical markings to Mira and Smiles. The one that looks like Smiley is 'Smiles Jr', the one that looks like Mira is 'Aki' as in 'autumn'. The one on his head is 'Buttons' and the one on his back is 'Fuyu' as in 'Winter'. The one biting the tail is 'Spartos' The rest are unnamed for the moment.
If you don't know Double head, he's a monster dog from 'Silent hill 3'. His head splits in two down the front and he's covered in bandages from what looks like burns.
