I am not aware of the date when such a suggestion arose, nor who raised the possibility.
AFAIK, Portugal did not operate cadaver dogs at the time. If correct, I can see no reason for them to suspect that the UK did. Can you?
It was raised in the early stages of Madeleine's disappearance when their skills might have been put to beneficial use.
SnipThe question is ... why did they not deploy the dogs in the first place at a time when they might have been of some value to the investigation ... like actually discovering where Madeleine was.
The dogs were on stand by; but had to be stood down; I find the fact far more intriguing that their use was turned down when it might have been of assistance to Madeleine rather than them being used to implicate her parents.

Police in the Algarve appear no nearer to finding Maddie 20 days after she was snatched from her bed in the family's holiday apartment in Praia da Luz. But the sniffer dogs are still being snubbed.
A senior UK police source said: "It is an absolute scandal, time is fast running out for this little girl.
"These dogs have immense capability. Their tracking skills are among the finest in the world.
"The dogs were put on standby to go to the Algarve within days of Madeleine’s disappearance.
"You would expect the Portuguese to make use of the best resources available to them, but they repeatedly ignore the offers of assistance."
The dogs include a spaniel whose sense of smell is so keen she can sniff traces of blood on a weapon even after it has been scrubbed clean.
But the source warned: "They work most effectively within a 28-day time frame. After that the scent becomes much weaker."
