The product itself is probably only suitable for so-called "Fußhupen". This can not be seen from the description exactly.
We bought the part of our Labrador puppies.
The search boxes are made of hard plastic. Today, with a little "harder" action of our "heroes", he has pulled out of the connectors and the plastic noses are broken there.
Because of the inappropriate from my line of sight variant of individual search boxes, base plate with uppers etc. I therefore give only 2 stars.
The plastic teeth for larger puppies, large dogs is too thin and the unit as a whole to light.
The idea itself is okay.
Our "hero" has recognized the "function" in the shortest possible time. For treats it hard to stop at an extra.
