Hector has had a Kong Wubba for a month and has great fun playing with it. However he can be destructive and even though this is a strong toy he has managed to dismantle it.
Why I am posting this warning is because inside the webbing casing there are two balls and not a kong shaped thing like you might expect. One ball is large and squeaks (the blue one) the other is a small tennis type ball which
only measures about one and a half inches across - THIS COULD CHOKE A DOG GETTING IT STUCK IN ITS THROAT.Here are some photos:

I am going to write to the manufacturers. I've taken the rest of the toy from Hector to avoid any problems.
I have looked at a couple of places selling them on the net and some do state that they are made up of
"Durable Reinforced Nylon Fabric Covers Two Rubber Squeaker Balls In The Small Size and A Squeaker Ball And Solid Tennis Ball In The Large Size."Val (and Hector)
