My puppy lays in his poop and pee in the crate. How can I stop this?

If you qualified for one then you'd have one by now. No dog will make you less anxious and won't help your other issues at all You can NOT train a service dog yourself, less so a guide dog and no shelter dog can be one. They have to come from companies the breed and train the dogs.

It takes TWO years to train one.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
