I think you are wrong, if I position a paper with text in front of my DSLR I can get all text quite sharp (because my lens is ****ty) even with F1.8 when holding it vertically, if I lay paper with text on a table and focus in the middle of that paper I can get that effect easily because this is how depth of field works. If you need proof I can do that in 10 hours.If you are focusing the center, it makes sense that anything else is kind of blurry, I don't see the issue here. Even with DSLR not everything is perfectly focused the whole time.
I find this perfectly normal.

On the other hand his dogs photo looks like a painting actually, and a quite photorealistic one. Thats something wrong with software in your case, looks like a filter applied.
