Here's my viewpoint. I want you to understand that this is completely my viewpoint. First off, it costs a great deal of money to have a dog/cat/pet taxi'd. We're talking twice to triple the normal fee for an equivelent size animal. Secondly, do you get your Grandpa mounted when he passes because you had some great memories with his prize horses mounted. To me it seems a bit morbid. For me, the most important thing to do is remember the great times you had with your pet, and let him go. Roy Rogers' dog Bullet and two of his prize horses were mounted, and it seems a bit morbid to me. Do what you want to do, but it will cost you quite a bit of money, and who's to say that the Taxidermist will capture the true "look" of you friend?
My 2 cents,
