Grime has been criticized since his involvement in the case for blatantly obvious reasons.
The McCann's and some supporters are concerned about the
Dogs indications.
Yet if they don't matter, then why the concern.

Keela, a human blood detection dog, is trained to pinpoint dried blood, while Morse, a victim recovery dog, is trained to detect the scent of human remains. Keela was directed to search the master bedroom, and found no traces of blood other than a drawer containing women’s underwear. Grime noted that isn’t uncommon because of the scent of menstrual blood.
Stockham and Grime said Morse detected two areas of human decomposition, near the bathtub in the bathroom of the basement, where Michelle’s body was found, and the carpet at the foot of the bed in the master bedroom.
Grime testified that Morse’s sniff rate increased when in the bedroom and basement, notifying him that there was the possibility of human decomposition. “All I can really do is tell you whether the dog gave a positive or negative response,” he said. “He gave a positive response [to human decomposition] in the basement and bedroom.”
The defense countered, arguing that the positively identified odor in the bedroom may have been transferred by investigators, a possibility to which the handlers did not deny. Defense attorneys argued that it is impossible to determine whether Morse’s alert was accurate.
“If it’s not confirmed that there was a dead body, you don’t know if it’s right or wrong,” defense attorney Jonathan Shapiro said.
Grime stressed that people will challenge positive responses, but not negative ones. “I am interpreting what is happening within the dog’s brain,” he said. “As soon as the dog entered the bedroom, he exhibited behavioral changes.

This is a US 2014 murder case, details of which can be found online. Not only is the cadaver alert in the bedroom questionable but two forensic pathologists have differing opinions of the nature of the death. The accused was found guilty of murder & has since had an appeal refused.
