Top! My dog loves his Kong about everything. You can fill it versatile and occupy his four-legged friends for so long. Whether as a reward, to reduce stress or to help when you learn the dog sometimes a few hours to stay alone - the Kong still is. Restless dogs who have difficulties with the teeth or in the car are ideal. At the treats the animal comes by licking or biting. The Kong is slightly elastic for dog bite and so the filling migrates closer to one of the two openings. When filling the creativity knows no bounds. Liverwurst, cheese, Pansenstückchen, cucumbers, bananas, boiled egg, mushrooms .... all fit in.
I can confirm that he is indestructible, even if you have a chewing experts sitting on the sofa. Especially pleasant I find that each fill the Kong lands directly in the dogs mouth and not on carpet and upholstery. A very hygienic matter.
Cleaning makes usually the dog itself. ;) From / flushing with water works well.
A little tip for beginners: loose fillings such as dog biscuits or treats I would always first fill. Not every dog creates it with the tongue up to the very top. Allen dog union Neubesitzern enjoy.
