If President Biden's dog Commander, AKA the White House biter, really is getting training -- as the administration's claimed -- he's been getting the wrong kind ... that's according to a former Secret Service officer who's dealt with other First pooches.
Marshall Mirarchi worked in the Secret Service's K-9 division for a decade -- including when Biden was VP in the Obama administration -- and he joined us on "TMZ Live" Thursday to explain why he's not so sure Commander's legitimately graduated obedience school.
According to Marshall, dogs NEVER get past a point of no return -- even a recidivist like Commander -- when it comes to training. He says they can always be re-trained, although the amount of time it takes a dog to fall in line is a different story.
Regardless, Marshall thinks all signs point to Commander not getting the proper direction, and he tells us what can, and should, be done to get him White House-ready again.
BTW, we spoke with Marshall back in July -- when Commander had bitten 7 people over 4 months -- and he claimed again the dog could be re-trained ... but based on Marshall's lengthy experience, it sounds like someone dropped the ball.
