Yep, as someone who rescued a Rottie x German shep when my little lad was 4, I do. I'm a sensible owner who has put thousands of pounds and hundreds of hours into my dog. Irresponsible owners who do not invest time and money into a dog are the problem in 99% of cases, and that is the same regardless of whether you own a chihuahua or a pitbull.
Fair enough. But my point still stands with these 2 because they are utterly irresponsible and stupid.
