How old is Lisl???
My female Mojo loves her kong, she hardly plays with other toys, just her Aqua kong - it's so bad I have at least 2 in reserve incase she looses her current one LOL
Hex is a real toy dog, he loves soft toys with squeakers, kongs with frozen yoghurt, he ADORES his Kong frisbee, his floating bumper for swimming, likes his linen tug , and his bad Cuz toy.
It's funny how different dogs like different toys - i showed it to Mojo and she just went "yeah whatever it's boring" LOL
Hex is definitely trying to get the ball out of the inside of the Jolly ball

So far he hasn't given up in frustration LOL
