Anyone flown with a pet using Delta cargo?

Thinking about taking a trip later this year and doing a direct flight with Delta and bringing my pup along. However he’s too big to go on the plane so would have to fly cargo. Looks like since Covid it’s because much more of a cumbersome process, have to drop off at Delta Air Cargo and pick up there as well, no guarantees they’ll be on your flight, etc. Just wondering if anyone has done this and how it went.
