Choker training was a thing in the 90's for police dogs and such, it works but it's slow, unpleasant and outdated. It's mostly about manipulating a puppies posture and building habits/routines. If you need the prongs it's because you started too late/don't know what you are doing and don't have any habits or routines to draw on.
Also with pits, people like Hassan get them from a shelter at 9 months old or w/e (well into adolescence) when they are basically untrainable for the next year+ and have completely missed the window on bite inhibition/soft bite. They are, as a general rule, bloodthirsty for anything on four legs and if you need spikes to keep it off my dog, so be it.....Better yet, wheel it around in a muzzle like Hannibal Lecter. They are also bred to disregard pain, so it's no surprise that the prong collar results in cuts. Getting a Pit from a shelter for your first dog is like getting a used Top Fuel Dragster for your first car.
Not only that, but rescue dogs in general suffer from shelter syndrome and need time to decompress to show their true personality and the true extent of their trauma.
A regular 9 month old puppy is already a difficult animal to work with, they're in the middle of being teenagers and are rebellious as hell. Add that to the experience of being a shelter dog for however long.
It can take up to three months for a rescue to decompress. A dog stops being an adolescent dog around 1.5 years, if not 2 or even 3 years depending on the breed (large and giant dog breeds like a mastiff, the leonberger, bernese mountain dog, saint bernard and even borzois just to give examples).
You're setting yourself up for a bigger challenge than needed simply by getting a rescue, but a shitbull rescue? As cute as I think some pibbles are, I wouldn't want to get one myself. And given my personal experience with a rescue, who was a relatively easy dog with very little trauma from before she was rescued, I don't think I'd ever want a rescue in the future unless under extremely specific circumstances.
Dogs aged 8-16 weeks are at their peak when it comes to trainability and how quickly they adapt to new situations. You miss out on that key period with a rescue. An adult dog is less of a gamble than an adolescent rescue but it's still a gamble.
Nothing against dog parks, they’re great, but I’m not sure they’re a great way for a dog this size to get exercise since they can’t really wrestle with most other dogs and they aren’t the kind of dog who run back and forth over and over.
not to mention, if Kaya is a reactive dog (there's a clip of her attacking another dog further back in the thread) and she's been bit by other dogs (like when Hasan exposed puppy Kaya to another, adult dog in a pen and spoke with glee how an afraid Kaya was the funniest thing in the world) she would not be a good candidate to bring into a dog park.
Lots and lots of ignorant or inexperienced dog owners go to dog parks, the vast majority of them are retards who go "oh, my dog is so friendly, he only wants to play" and let their fully grown golden retriever barrel straight into your dog, as if it's an acceptable way to greet a strange dog.
Dog parks are good in theory but I've witnessed too many attacks and fights in dog parks.
