"I train search dogs for many different purposes. In the end, these dogs must be able to work in all imaginable environments and situations. Part of the basic training involves introducing what we call target scents. That is, the substances that the dog must find and mark. In the the process requires you to be aware of exactly what you are presenting to the dog. Then you need access to a variety of equipment on the market in the form of scent carousels, containers and consoles. I prefer carousels a more independent search and is easy to handle from a hygiene point of view, I thought a good carousel should not be simple and robust. It should not contain more parts or functions than it should also be cheap because it is used during a limited but still important part of the training. Fifth Paw has succeeded in exactly what I hoped for. I can warmly recommend this scent carousel to anyone who wants a really good scent carousel for their training."
