Mine have soooo many sqeaky toys they kill them a few hours after so i have to get one everytime i go to walmart to replace it i have a few that the have'nt killed in a while they have ducks,pigs, grunt toys but there favorite is this toy that's shaped like a potato and it plays that song
WHO LET THE DOG OUT HOHOHOHOHO that's the only part of the song it plays and they LOVE it they go crazy for it.

They come to bed with me so i make sure they don't have any toys in the bedroom before we go to bed.
