here's also an Express article that since has been pulled/removed from the public domain ("Questions for the McCanns") which said:
Why did a dog detect the smell of a corpse on your clothes?
A British dog trained by police to find dead bodies is alleged to have detected something on Mrs McCann’s bible, jeans and T-shirt and also on Madeleine’s favourite Cuddle Cat toy. Kate McCann is believed to have replied that she came into contact with at least six corpses in her work as a doctor. And it is possible Madeleine’s toy could have become contaminated from Mrs McCann’s clothes.
Kate took CuddleCat sometimes to work
No source found for this claim.
The ‘smell of death’ could have come from rotting meat that Gerry McCann was taking to the local rubbish dump from time to time
Not the McCanns, but 'a' friend, an unnamed source claimed this.
If Madeleine's DNA were to be found in the boot of their car, it may have come from the children’s dirty nappies they claimed they were carrying in the boot.
Again this 'friend', an unnamed source was speculating about it.

Whilst in the villa, a gardener would arrive every week or about every 15 days. This was organized by the estate agency. The gardener would leave black rubbish bags near the gate, and on at least one occasion, I used the vehicle to remove these bags. The collection of rubbish in Portugal is not made as it is in the U.K., and for this reason, it was necessary to take the rubbish to a tip (disposal area) which was called 'recycling area' near the back of the Ocean Club. I used the Renault Scenic for this reason on many occasions.
On one occasion, I believe it was on July of 2007, I took Patricia to the supermarket. We carried bags in the boot (trunk) of the Renault Scenic; bought various items including fresh fish, shrimp and beef. When we unloaded the shopping bags, we noticed that blood has run out of the bottom of the plastic bag. After this shopping trip and still in the month of July 2007, I began to notice a strange odour in the car. I did not give it much importance and assumed it was likely due to the leakage from the rubbish bags or from the blood which had escaped from the shopping bags. As a result, we removed the carpet from the boot (trunk) in order to clean it. I tossed (beat) the boot carpet to remove any particles and cleaned it with a wet cloth and left it to air out.
