Interesting thread. I've read a lot of it, but not all of it.
A friend turned up on our doorstep this morning covered in blood and mud. She was sobbing her heart out and was clearly in shock. I guided her inside so she could explain.
Turns out she'd been out walking her dog in the local park, accidentally let go of his lead and he instantly bolted. He went straight for another dog to attack it, and that other dog's owner tried (understandably) to protect her pet. She'd ended up with a deep laceration to her hand from my friend's dog and the other owner called the police. They attended and took details. They said to my friend that they wouldn't be pressing criminal charges (against friend) but they did want to visit her at home this afternoon to discuss her dog.
This dog, in the past, has chased AND KILLED cats, but also waterfowl like ducks and geese. When I had a baby I made it clear that in no uncertain terms was her dog ever to go anywhere near my child. She understood and respected this.
Today, she stood in my kitchen sobbing and said she didn't want him (the dog) any more. Finally it appeared she was coming to her senses that he is a dangerous dog.
Oh yeah, the breed? He's a Staffie. Staffie owners are so quick to defend the reputation of Staffordshire Bull Terriers, claiming they wouldn't hurt a fly and are completely safe around children. The truth is NO breed of dog is completely safe. Not even the 'big softies' like Labs or Retrievers. We had a Collie cross (died three years ago prior to having children) who lived with two house rabbits and was the softest, daftest, sweetest dog... but I never EVER trusted him alone with the rabbits even for a second because at the end of the day, he was still a dog and all dogs have a breaking point and can snap, especially if provoked.
My friend's dog is not, in my opinion, a 'nice' dog. He isn't friendly, he isn't gentle, he isn't a softie even though my friend has consistently claimed he is. He has killed cats and water birds because he's an aggressive dog, regardless of his breed.
I do not yet know what came of the police visiting my friend. I am waiting to hear and I have genuinely no idea what the police might say. After my friend had left here this morning, I said to my partner that if a dog is capable of killing cats and large birds then it is perfectly capable of killing a child. I'll leave that there.
