The first one was a cucumber (Ravelry link). It must have looked very yummie, because the dog ended up 'eating' it.
The second one was an earthworm (Ravelry link).
I actually made two earthworms, one for my kids and the other for a birthday gift for friend's son along with a kids' fishing pole.
The third was a garlic(Ravelry link). Obviously the dog doesn't like garlic because this one has been completely untouched unlike the cucumber - or could it be because it's made out of acrylic while the cucumber is made out of wool!
