@sondancer1978 Go slowly, one hour for a dog with separation anxiety is a lot. Start small with only 1 minutes and you're still insight, just the crate door is closed. Slowly increase time. After you're more than certain that your dog is doing okay, start lenghthing the distances and times until you're eventually out of sight, but still inside the house. If that goes well then try going out the door for a minute. Come back in and don't make a big deal about it, then go give your dog a lot of praise. Once your dog stops reacting to the one minute, up the time slowly. Then wait until no reaction (treat and praise heavily)
Give him safe toys to keep busy. Something like a kong with his a delicious treat. Start training him to be quiet and use a quiet command. Id recommend watching its me or the dog to see different training methods in action. There are a few videos with dogs who have similar problems.
Show your dog that when you leave, you will come back. And treat your dog when you come back so that you leaving will be associated with a good thing bc everytime you come back, you give a very high value treat. Also give a very high value boredom reliving toy that your dog only gets when you leave. And the treat should also be only given innthis situation. You really need to give your dog positive associations with ppl leaving bc its ckear you're dog doesn't have many of or any those
Please go slow, if you work too fast, it'll just set everything back. You have a dog with anxiety. The process is not going to be easy for you, but its much much worse for the dog. Go slow, have patience and remember than even a small improvement is an improvement and you need to give your dog a lot of praise and treats for that. Don't be afraid to take a step back if your dog isn't doing well with the current step, it's not that the training is failing, its just that your dog needs some more time.
Id recommend doing your own research on different training methods for separation anxiety so that you can choose a method that works for your situation. I totally recommend Victoria stilwell (its me or the dog)
