A woman was forced to undergo a skin graft after an out of control dog bit her leg.
She was walking her three dogs when she was attacked by the Staffordshire bull terrier.
The pet, named Dave, will be destroyed if it is not kept muzzled in the future.
Its owner Jane Baker was convicted after a trial of a charge of having a dog dangerously out of control and causing injury.
Kirklees magistrates heard that the victim was walking her two British bulldogs and a French bulldog in the Cleckheaton area on December 20.
She saw two dogs belonging to Baker and tried to coax them back into their house as she was concerned about her own pets being attacked.
Bill Astin, prosecuting, said: “She saw the defendant who lives at the address and asked her to get her dogs back in. There was an exchange of language and one of the dogs bit her on her leg. This broke the skin and it started bleeding.
“Members of the public intervened to get her home safely.”
The woman was taken to hospital and then a further appointment was made for her so see a plastic surgeon. She had a skin graft and several follow-up hospital appointments.
The court heard that she said she blamed the dog’s owner and not the dog as this was how it had been taught to behave.
Cheryl Ford, mitigating, said that Dave must have reacted over a perceived threat to his owner.
Deputy District Judge James Hatton ordered Baker, of Turnsteads Drive in Cleckheaton, to complete 15 days of activities as part of a community order.
The 45-year-old also has to pay £300 compensation, £200 court costs and £60 victim surcharge.
Judge Hatton made a contingent destruction order.
This means that Dave will be destroyed if he is not kept muzzled at all times whilst outside.
