I think it is a misconception that eating fat causes fat.

Look up the thread that @Mike CHS started (?) about all the Keto foods/plan.... or maybe it was @Devonviolet , but several have been following it and lost weight and there is alot of "fat" in that diet.
She also does not like vet visits and outweighed and outmaneuvered (and out leaned and out squished) the technicians . . .
That is too funny!
Our 2 LGDs are the same way. We have gone to the Vet since they were puppies, and it's never traumatic. But, they don't like being away from their goats. In fact they don't like it when I take their goats to the barn, for weighing or meds, etc. They start barking as I lead them away. 
It's ok if she bonds to your family. Let her have house time with the family in the evenings, then back outside. She can handle both worlds. As I write this, our male, Trip is asleep on the floor. He relishes house time and will come to the door and "ask" to come in. Our female NEVER comes in and the few times I tried, she utterly freaked out. So there you have it, each dog is different. Your vet is missing the mark, you don't so much train the dog to you, as much as the dog trains you to her. Somewhere in there is a happy medium.
