The thing is, other professionals who have trained cadaver dogs, some from forensic police training have said that these dogs can give false alerts to decaying vegetation.
Grime says Eddie was an 'enhanced' victim recovery dog, yet the only training Eddie had to become this 'Enhanced dog' was through going to America and being trained to alert to the decaying human bodies, which Grime says smells the same as the decaying pig Eddie was trained on at first, in fact he goes on to say that it was impossible for the dogs to tell the difference between the two and it was impossible to train the dogs to tell the difference between the two.
Now we are to think that Eddie is a super dog better than any other cadaver dog that has been trained in Britain because he had training in America too, even though it really means nothing.
People who have forensic knowledge of what these dog will or will not alert to have said that an alert by a cadaver dog when there is no body to be found needs to be taken with caution as the dog may be alerting to the scent of something such as a bloody rag or a sanitary pad that could have been in the place where the dog is alerting.
Eddie alerts to blood, there is no doubt in my mind that Eddie alerted to blood on the key fob as Keela alerted to it too.
Therefore Eddie could well have been alerting to something that had had blood on it in the bedroom, and was not there any more but the scent remained, or from something that could have been walked in from the garden and had settled in the grout of the tiles, or the scent could have gathered in the bedroom from the garden.
So the alert in the bedroom can only be taken with a pinch of salt in my opinion.
