I'm surprised the dog holes last. I have some benches made out of MDF

dog holes in it but was afraid they wouldn't hold up.

I wonder if the term "dog holes" are being stretched here. I think Leon uses the holes with the Festool clamps, which do not rely on the strength of the hole or having a thick table. Traditional dogs require at least 1 1/2" table thickness. I use 3/4" round dogs and hold-down clamps. I have a re-purposed dining table that has a 3/4" solid wood top. I glued pieces of 3/4" baltic birch underneath, then drilled 3/4" holes using the Leevalley 3/4" drill guide to drill the holes with a hand drill. It works really well and seems to be holding up.

Perhaps but I've seen in-line bench clamps used with MFT tables.

Two of my tables have an 1-5/8" solid core door, one with MDF and the
other, melamine, sacrificial tops. I also have a couple of 1-3/4"
maple-top benches but I'm not concerned with them yet. Yes, I'd like
to use the Festool style clamps in the MDF topped bench, if it's not
too thick, but also in-line bench clamps, dogs, and similar.
