No. And yes.
Could I love the right dog no matter what the look? Sure.
Do I want my Filas to look like Filas? Yes. But not to nitpicky conformational standards, measuring the nose, the length of the ears, where the tail sets, etc. to a quarter or an eighth of an inch. That's just silliness.
First it has to be a Fila on the INSIDE. Then the outside needs to be put together in such a way as to facilitate the inside. The extra long back legs and higher hips, for example. Speed, strength, stability and agility to be able to deal with wild cattle and jaguar -- or pretty much anything that can be herded or hunted. Let's face it, hunting jaguar is the ultimate test of whether or not you can herd cats.
The body needs to be able to accomplish what the mind and heart set out for it to do.
I don't want my Filas to look too much like Bull Mastiffs or Great Danes because I know that some of the show lines from Brazil have infused their lines with Bull Mastiff and/or Great Dane to get dogs that are easier for the average person to handle. They are also infusing the Fila with the health problems of those two breeds! In that way I DO care, very much, about the looks of my dogs.
Would I love Kharma less if she didn't have the look of the historical Fila? Or Bimmer if he looked like a modern GSD? Or Tallulah if she wasn't such a beautiful example of how an APBT looks? Absolutely not! Love is for what's on the inside, what makes them who they are.
