Looking for dog owner advice

I’m having some problems with my dog and the children in the local area.

For context: I have a 1 year old dog. She is a large breed, and the breed is not named in the dangerous dogs act. We live quite close to the city centre.

Our dog, while large, is in no way aggressive or hostile - quite the opposite. Although, with her being big I can completely understand why people can be hesitant around her or even scared - I often find people cross the street to avoid her. It’s actually kinda sad.

There’s loads of kids who play out in our street and the gardens round the back. I am familiar with them as they go to the same school as my own daughter - and have in fact caused her major hassle at school. Im also aware that there have been physical fights in the street caused by the behaviour of these children. They’re all 10 or younger, and I try to give them the benefit of the doubt, but woweeee the use of slurs, swearing, aggression is really something.

For the past few months these kids have been harassing me and the dog. It started with them asking if she was a “canine” and being told that having her is illegal. I kinda thought at first that maybe their parents told them owning a dog is illegal as a means to get out getting a dog for them. I’ve tried explaining that canine and dog are the same thing and that it’s completely legal to own a dog. Multiple times. Every time I see them in the street they shout at me about my canine and her being illegal - and for a while it was laughed off or ignored, no problem.

The issue I’m having now is that they’re now harassing me while in my own garden as well - which is gated and they shouldn’t be in. It started escalating when a huge group approached my fence, started shouting at me that my dog was illegal, and then trying to antagonise the dog - barking at her, growling, throwing things at her, anything to get a reaction. My dog has never reacted or responded, and generally pays them no mind, but it doesn’t make it acceptable behaviour. I also have reason to believe that they’ve been coming into the garden and taking her toys - but that’s a different issue I guess.

I’m at my wits end honestly. I’m not worried about my dog or her behaviour or aggression - she’s never shown any sign for concern. We have an autistic child and she is incredibly patient and tolerant. We have put a lot of time and care into training. What I am worried about is that ALLLL dogs have their limit - I’m living in fear that a dog (not even mine specifically, any dog) is going to snap at these kids and that things for my family are going to get worse or we’re going to lose our dog. I have been very patient with these children until today (prior I have told them on multiple occasions to leave us alone and stop) - when they stopped me in the street and once again started harassing us and my response was much more blunt than usual. I’ve seen their parents run to their defence for less.

I don’t feel I can approach the parents because I know it will be dismissed. My dogs not actually attacked anyone so I don’t think there’s anything the police or a dog warden can do? But I’m really concerned that they’re going to get themselves in trouble and it’ll be blamed on an innocent party.
