We have selected for our Labrador Large Kong, use the Kong almost every day and he is after almost 7 years of use (the first two years, we use the small Kong, they would but now swallow) still perfectly! We give him an average of once a week in the dishwasher.
Especially great are the Füllmöglichkeiten. One can also googled for suggestions, but you will also find yourself quickly get the hang of.
Our dog likes best (I mentioned yes- she's a Labrador, so please do not be surprised):
First Layer two, three small biscuits. then reinmantschen a banana and finish with another two, three biscuits. The banana we replace like with cheese, either Harz or Limburger. This guarantees fun and employment for at least 20 minutes. And for a 30 kg dog like that means something!
Our conclusion: Kong is the best thing there is for dogs keeps forever, guaranteeing eternal fun! Especially this one, I can very empfehlen- our absolute number is 1. And we have almost all!
