Is a mercedez benz really worth $90,000? To some, yes, but to others, no. These dogs are worth it to many, even as pets because they see the animals as being amazing. However, I don't like the overdone muscular pitbulls. These dogs are exceedingly powerful and when bred properly, are great guardians. They are naturally protective, like mastiffs( not surprising since many do have mastiff blood). However, these dogs tends to lack stamina and endurance required for other fields of work, such as hog dogging so I wouldn't pay that much for one.
Neither overly muscular ambullies nor mastiff mix banddogs are pit bulls.
The APBT is NOT a good guardian and is NOT naturally protective. They are bred to be friendly to EVERYONE, so if you get an APBT and expect it to be a guard dog, you'll be poorly mistaken.
My dogs were free, and if you walk down the street I'm sure you'll see half a dozen pit bulls. Why pay multiple thousands of dollars on a dog when you'll be spending multiple thousands of dollars on them within the first few years of their life? Doesn't make sense to me.
