There's no way they did this shit to a house
Yeah looks like someone lifts his harness from behind the wall.
It's possible, a typical balloon can lift some 14 grams and a dog this size might weigh 12 kg. The weight of the strings gets more significant with more balloons so it's not possible to float a house like in Up (which is what the parent comment is referring to).
This remembers me something that happened here in Brazil. Some years ago, a Brazilian priest attached himself to a thousand helium balloons. He flew a long distance until he disappeared. After some months, his body was found on the ocean.
Can't beat lawnchair Larry
A taste:
Larry planned to sever the anchor and lazily float to a height of about 30 feet above the backyard, where he would enjoy a few hours of flight before coming back down. But things didn't work out quite as Larry planned.
When his friends cut the cord anchoring the lawnchair to his Jeep, he did not float lazily up to 30 feet. Instead he streaked into the LA sky as if shot from a cannon, pulled by the lift of 45 helium balloons, holding 33 cubic feet of helium each.
He didn't level off at 100 feet, nor did he level off at 1000 feet. After climbing and climbing, he leveled off at 16,000 feet.
At that height he felt he couldn't risk shooting any of the balloons, lest he unbalance the load and really find himself in trouble. So he stayed there, drifting cold and frightened with his beer and sandwiches, for more than 14 hours. He crossed the primary approach corridor of LAX, where startled Trans World Airlines and Delta Airlines pilots radioed in reports of the strange sight.
Would recommend watching the Hughbees video about him.
Pets don't want this. Don't do stuff like this to pets for internet points or real money.
Pets don't want to fly you mean? :P
I used to attach paperclips to helium party balloons until it was neutrally buoyant. It looked cool that it was sorta like antigrav technology when in reality it was just Newtonian shit.

Larry's the ultimate madlad! Lived to tell the tale too!
That's not a thousand balloons.
