Owner training allows handlers to choose some non-traditional breeds or higher energy individual dogs that match their active lifestyle. Some people end up with dogs that have more energy than they bargained for or they inadvertently ramp the dogs up by how they interact with the dog (what they reinforce without knowing it) like jumping up on their arrival or excited behavior in general). While it is important that these dogs get enough appropriate mental and physical exercise (avoid mindless ball chasing as it drives up adrenaline), it is also important that these dogs be taught how to relax. The relaxation protocol created by Dr. Karen Overall is one tool that they can use to help teach a dog to calm themselves.
The relaxation protocol is an incremental way to teach a dog to calm himself in the face of distractions. It lays out a training process so the handler can add distractions in small enough bits that the dog can succeed. There are many layers to this protocol and they are laid out in detail for handlers to follow. A bit of creativity will be needed to adapt some of the distractions for people with balance or mobility challenges. A side effect of the protocol is building a reliable stay behavior which is ideal for service dogs. You can combine the protocol with a mat to more easily generalize it to different locations.
Here is a link to the text-based protocol.
Here is a link to audio clips that you can listen to while training.
If your service dog in training has a short attention span is antsy or has trouble focusing, it is worth trying the protocol. It is a great foundation to start training relaxing with a puppy too!
