Hahahaha! Angela, you are pure

Abi likes pigs ears, not so much the hooves, although she will "nibble"
every now and then.
Pugsley is more into sleeping than chewing and Bubs will chew on
a Pedigree chewy but nothing else!
Bully sticks were tried on all of them (except young offender as yet) and
they all (the gang of 4) turned their noses up

Tried the salmon skins but to no avail and have pretty much
given up trying anything else due to the broken "bank"
