I bought the small size Kong Wobbler for my baby yorkie and when I first received the Kong I was doubting she will like it or able to use it coz the weight. Surprisingly, she master the Kong quickly. Well, it took her approx 30mins to finish one meal where normally less than 2 mins if in the bowl!! I wish it would have the function to make it harder to get by adjusting the size of the hole smaller. I use tape around the hole to make food harder to get, which works just fine.
I am very disappointed with this kong wobbler, I thought it would be ideal for my 7mth old staffie, it lasted 2 days of which she actually had the toy for for about 3 hours in total, now it wont screw back together as she managed to chew thru the plastic where it screws on!
This is a strong toy which I highly doubt will need replacing. It's a great idea for challenging and feeding your dog at the same time, but the large one is too heavy for a medium sized dog (and the small one can't fit a medium sized dog's breakfast in), and the toy doesn't come with any instructions (for inexperienced dogs). If you are only giving a dog a treat rather than a meal, I recommend the Kong 'Stuff a Ball' instead, which is lighter. My tip is to let them get used to eating from the cone of the toy before screwing on the ice-cream.
I bought the large one for our young collie cross and she just loves being able to smack it hard and get treats from it. Definitely a success with her! And rugged and easy to fill and clean for me. What more could I ask!
My border collie loves his kong wobbler. It never fails to keep him entertained, for longer than most of his toys.
I wanted something which would keep my dog occupied and make her work for her food; this is perfect. It opens easily for filling and cleaning and easily holds a whole meal. The erratic roll keeps my dog on her toes and it's very robust. The small size is quite large compared to my small dog (a Bichon Frise) but she manages fine.
