I'm posting some links/info on how cadaver dogs work (bolding by me in the quotes below). There is also a lot of good info about how cadaver dogs work on Dylan Redwine's threads.

Cadaver dogs: attending camp with the canines trained to smell death
"Another search that sticks out in Hreniuk’s mind was in Slate Hill, New York. A farmer’s dog brought the body of a baby to his backyard. The farmer reported it to state police and Hreniuk and her dog were asked to search for more evidence. “We were told the body was missing a foot, so I imagined that was what we were looking for.
“It was a cold day in February, and snowing pretty heavily. I was finishing my search area near a dump that was on the farm property. My dog, Remy, showed interest in an area and finally pinpointed the source and pulled up from the snow a clear plastic bag that had blood in it,” said Hreniuk. She radioed for the police who were waiting in the farmhouse. In the meantime, Remy kept working through the snow, and found some type of patterned material with blood on it. “Since it was evidence, I didn’t touch it. The blood was confirmed to be human at the scene.”"

What Cadaver Dogs Are Sniffing For When They Look For a Body | Inverse
"Human bodies decompose in five basic stages, and each of those stages produces dozens of different odors. In an attempt to classify them, researchers from Oak Ridge National Laboratory and the University of Tennessee teamed up with the FBI to build a “decompositional odor analysis database.” In a 2004 article in the Journal of Forensic Science, they explained their process: First, they buried four bodies in graves between 1.5 and 3.5 feet deep and, over the course of the next year and a half, used traps to capture the air that emanated from the rotting bodies through the ground. After analyzing 374 samples from the graves, they found out just how many volatile chemicals the human body makes when it decomposes: a whopping 424.
Many of these scents are likely identifiable only by trained dogs, but a few will stick out even to the common human nose: cadaverine, putrescine, skatole, and indole. As Inverse has explained in the past, these compounds smell particularly rank:"
In other articles I read, it was stated that cadaver dogs have found bodies buried 12 feet in the ground and even underwater. IMO if Bella's and CeCe's bodies were put in bags, it would not have deterred the decomp scents from being left behind.
JMO but I think LE did the searches intentionally while CW was being interviewed outside the house, so as to unnerve him and have his reactions recorded. Same with the reporter's question about the shirt.
