It wasn't so much lifting them up, but for sure, when I was having a grooming session, using my table, I had to have those not being groomed away from the g.table so I could safely return the one being groomed, to the ground. That was the point when that one was 'fair game' so after the first time when the others would pounce on the one being put on the ground, I moved them all away from the grooming table.
It never happened in the UK as the breed is normally judged on the ground, but once out in Canada, a judge wanted to see them up on a grooming table. I was showing a hound who must have been around 80 lbs and when I saw what was going on, I blanched. Had I not got him up there in one go, it would have been curtains. After that, I trained all of them to put their front feet up on the table, so I could heave the rest up without doing myself a mischief.

Any dog up off the ground would be seen as 'vulnerable' to others. It's not jealousy which may look like that to a human, but it's not an emotion a dog can have. What looks like jealousy to us, is just the opportunist dog pitching in, looking for whatever is available.
And btw, if you do lift a puppy off the ground, make sure you do it slowly, and return it to the ground slowly or it's like going up a fast elevator, to a dog.
