Banning all American “XL Bully” breeds is unfair and would punish well behaved pets, according to the Dogs Trust.
Owen Sharp, chief executive of the charity, said there would be a “multitude of problems” with attempts to outlaw the dogs following the attack on 11-year-old Ana Paun on Saturday.
Speaking on Monday, Ana said she wanted to see a ban enforced after an XL Bully left her “screaming for help” when it sank its teeth into her arm and bit her shoulder when she was walking to the shops near her home in Bordesley Green, Birmingham.
Suella Braverman, the Home Secretary, said she had commissioned “urgent advice” about banning the dogs following the attack.
But Mr Sharp warned such action could leave many families deprived of their well behaved pets.
He told BBC Radio 4’s Today programme: “We just don’t think breed-specific bans work.
”Unfortunately there are poor owners and a larger number of poor owners with these dogs.
”There would be a multitude of problems in trying to implement a ban.
”It would be purely based on size and physical characteristics and it would draw lots of very well behaved dogs into it and possibly ignore others.”
He was joined in the interview by Sophie Coulthard, an XL Bully owner, who claimed a “moral panic” had been whipped against the breed in the wake of the Birmingham attack.
She said the dogs should not be banned but instead called for restrictions surrounding breeding.
The crossbreed, which can grow to the size of a mountain lion, is said to be responsible for 75 per cent of all fatal dog attacks in the UK in the past three years.
Kit Malthouse, a former deputy mayor of London under Boris Johnson, led a crackdown on dangerous dogs in the capital more than a decade ago.
He said new legislation should be introduced in this autumn’s King’s Speech to ban sales, breeding and imports of XL Bully dogs and bring in “neuter and muzzle” orders to prevent further attacks.
He also said there should be an amnesty for owners to hand in their XL Bullys if they cannot control them, so that they could be cared for in a dogs’ home or put down.
A Government source said “all options were on the table” to tackle what Mrs Braverman has described as a type of animal posing a “clear and lethal danger to our communities”.
