I see far too many people locally in my park with dangerous looking dogs (the ones that require harnesses). A group of 2-3 men were exercising 3 dogs with harnesses in tennis courts the other day. I saw another dangerous looking dog in the park with teenage or early 20s couple with young baby.
I know of people who have dogs they use for fighting - on a nearby local estate, witnessed this before lockdown. No one dares to report them or get involved.
My family growing up have owned a Labrador, Weimaraner, and Afghan Hound (all very well trained and good breeders) and close relatives owned a Doberman (lovely soppy dog but a guard dog too) and other close relatives long and short haired German Shepherds. The latter relatives rehomed a German Shepherd that was either too interbred or had behavioural issues, the soppy long haired German Shepherd and the other one killed a family parrot when left alone. These were people who “knew” dogs.
I personally don’t trust many dogs. Even my nana’s first miniature poodle could be a vicious little bugger!
Any dog can attack. My DM was bitten (not too badly) as a young child by a Scottie dog in the street, made her scared of that breed!
Too many owners buy dogs and don’t train or research into them.
Very sad for this poor boy.
