How much should my dog weigh?

Question

I have a pure bred German Shepherd male.

Age: 2 and a half years old (because of his puppy like behavior)

Weight: 95-100 pounds right now

Will my dog drastically increase in weight or mass assuming a healthy diet and plenty of exercise.

Answer 1

no he is in the right range

Answer 2

He really should not get any bigger than that. 100 pounds is large for a Shepard.

Answer 3

My vet said the way you can tell is by feeling the rib area.  If you can feel all their ribs and there isn't a lot of fat around them, then he should be fine.
