At Masters Tingalpa yesterday afternoon they had a box of Hear Doggy toys clearing out at $1 ea
These are squeaking dog toys, however they are at a frequency that only your dog can hear, so much less annoying!
there were 3 styles
The Brown flat beaver
The Flats Rabbit
The flat skunk

they are in a box on the ground in the far right aisle (in the garden department) where the dog beds live.
