I think you were incredibly unlucky to have two such similar incidents happen in a two day period
Well perhaps you don't get out much. I've had similar incidents in a period of 4 hours.
A gated playground, with a bit sign saying NO DOGS,
So a young lad about 18ish brings his small siblings to play there.
And the family dog, which he lets go of.
I say to him "The dog is not allowed in here, really"
He ignores me. Another woman comes along and says "This is a kids playground. Dogs are not allowed in here"
He ignores that too.
Then, a huge 18 stone tattooed beardy bloke who had erstwhile been leaning against the fence watching his daughters going down the slides, and who had obviously been watching, comes up and says.. . .
"Get that fucking dog out of here. NOW!!"
Not in a friendly manner.
Brave ignorant 18 year old scuttled off shitless.
Neither me or the other woman persuaded him. It was only the threat of a big burly bloke and possible violence that sent him off on his way.
So then I went up a local footpath, and a woman was walking 2 dogs.
They were untrained and hurled themselves at me and my husband.
They were not unfriendly. I wasn't worried that they were in attack mode.
But their enthusiasm was unwelcome. I do not like dogs and am allergic to their snot.
They actually "hurled" themselves at us. Their dog bodies actually hit my husband's body above his waist. It was MAD! I stepped back. My husband took the brunt of it. I turned away and escaped the worst.
I go for a walk, and I don't mind at all well trained dogs walking by. Having a sniff. A well controlled dog having a sniff at you. All fine. But when they see you from a distance, go into alert mode, and then make a beeline for you, and then hurl themselves at you, barking, then you have to start to wonder if their owner has any control at all.
Clue: They don't
So to be honest, I wouldn't find it at all surprising if the pp had 2 dog incidents in two days. I've had 4 and more in just one day.
Bought my house in the 80s. Lots of field walks. The occasional person with a well trained dog.
Now: The fields are full of barky dogs. Farmers complaining that the dogs are responsible for their sheep miscarrying. Fewer lambs being born. A random dog just running about loose and barking can trigger abortion.
Some dog owners are idiots.
