Place training is one of the most useful skills because once learned, you can use it for so many things. This is where you send a dog to a mat or bed on command and you are able to leave them there until you say they can get up.
To get started get your dog to follow a treat onto the bed and reward heavily so that your dog loves being on there. Every time your dog gets off, take them back using the leash and don’t give a treat afterwards. Show your dog that a release word like, “ok,” means he can get off the bed/mat. When your dog hears this word is the only time he can go so make sure you are consistent. Remember like all training to build this skill up gradually.
