I would agree with you; it would be a complicated, time intensive process; if ctb by others means would'nt kill you, the convoluted bureaucracies of dignitas and Pegasus most certainly would. In attempt to separate fact from fancy, I will be making it a point to contact them. However, according to their propaganda, it is "thumbs down", if you will.
The price for both is not very expensive; I am fortunate that I have the money and that the respective services provided are fairly price commensurate. One of them (am uncertain as to which one) will permit a canine companion. Again, so much of this is enshrouded in a mystery that can only be resolved with direct contact. Respectfully, I would take no one's word for it, short of direct contact.
