LOL, I've had many dogs in my life, every single one was the best dog who ever lived
I've never paid a penny for a dog except for the $55 or so fee it took to get him out of the animal shelter.
But it's your decision, your dog, your money. I'm not about to try and tell you what to do with it. None of my business.
But if you wanted to kill an hour or so and have some fun, going to the local shelter and playing with a few dogs is about the most fun you can have for free. It's also fun for the whole family
