This was a case legally entitled Regina versus Laurence, in effect the Queen was prosecuting her own daughter.
The Princess Royal - or Laurence, Anne Elizabeth Alice Louise - pleaded guilty to being in charge of a dog which caused injury in a public place under section 3(1) of the Dangerous Dogs Act 1991.
Dotty the guilty royal dog bit two boys, cousins, aged 7 and 12. The boys were riding their bikes in Windsor Great Park.
According to Dr. Roger Mugford, a dog behaviourist, Dotty's problem was "excitement at bicycles."
This was revealed to a district judge at East Berkshire Magistrates’ Court in Slough yesterday.
The boys attacked by Dotty were on a family cycle ride.
The Princess Royal's solicitor said Dotty, clearly a discerning bitch, had “a high degree of interest in bicycles.”
After the biting incident, Dr. Mugford went to Dotty's palatial home at Gatcombe Park for a two-hour psychiatric session with the bicycle-fixated canine.
According to The Times, Dr Mugford recreated the 'bicycle incident'.
He rode "round the garden making a lot of noise. The dog became excited, but when he repeated the experiment after firing off a canister of harmless gas to divert her attention, Dotty showed no further interest in bicycles."
So, there you go, if you are "excited" by or have a "high degree of interest" in bicycles, gas yourself silly and the unnatural urges will go away.
