A seven-year-old girl has been attacked by a dog in an "horrific attack" while playing in a park.
The schoolgirl suffered bite marks to her legs and cuts to her head during the attack, which happened in Gorsedale Park in Wallasey, shortly before 8.30pm on Monday 17 July.
She was taken to hospital where she received treatment and has since been discharged to recover at home, Merseyside Police said.

"I want to appeal to anyone who was in the area at the time of the incident who may have information which could help us with our investigation to come forward as soon as possible," Detective Inspector Kerrigan added.
"You may even live locally and have CCTV, or have been passing in a vehicle and captured dashcam footage – if so, we want to hear from you.
"This case highlights in the starkest terms the potential dangers of dogs, and I would appeal to anyone with information about dangerous dogs in their area to contact us so that we can take pro-active action.
