• A Staffordshire Bull Terrier mauled its owner to death after eating crack cocaine, an inquest heard.

Major was the equivalent of eight times the human drug drive limit when he latched onto Mario Perivoitos's face and neck moments after his owner took part in a BBC documentary.

Mario, 41, had been filming with a camera crew for the BBC programme Drugs Map Britain when he fell into an epileptic fit and attacked on his bed.

Nicholas Carmichael, an expert in veterinary toxicology, revealed that samples of cocaine and morphine had been discovered in Major's urine.

Mario Perivoitos, 41, was trapped in his flat for half an hour and was heard screaming 'get him off' by neighbours, who eventually got a crowbar so paramedics could get inside

Mr Perivoitos was a heroin and crystal meth addict and had been taking part in a documentary about addiction and anti-social behaviour, according to neighbours

The exact reading and measurement of cocaine was not stated but Mr Carmichael said: 'We undertook two analysis of blood and we did not find any toxins but we also received a urine sample and identified a cocaine metabolite and also morphine.

'It is very likely that this dog had consumed drugs, probably eaten them.

'It is almost impossible to say whether that will make the dog attack but it does make them respond abnormally.

'They become very excited and agitated, it is highly more likely that this attack happened because this dog had taken cocaine.

'In my experience with Staffordshire Bull Terriers if they think they are in a dominant position its response must have been to attack.

'The dog was eight times the drug drive limit.

'The dog had clearly taken it and, whether it had eaten it or taken it in by smoke, it is likely to have been a factor in the dog's behaviour.'

Before becoming a vet pathologist he spent over a decade as a veterinary surgeon.

The dog  attacked the man outside his home on this road in Wood Green, North London, while the programme was being shot
