I got to thinking about this --- primarily it's your husband's anxiety that needs attention. Have you considered listing everything that was going on with his dog that hanged himself? You could list all the particulars of then vs all the particulars of now. As in first dog wasn't a "working dog" - this dog will be. You will put equipment on cue. This fence is different than that fence. You will add modifications (coyote rollers, baffles, etc ) as warrented. This dog will go on regular walks. This dog will not be out on a line without supervision. etc etc etc. Because, really, assuring him is what this is all about.
