Its so-so. I use it sometimes to get a quick look if I'm out of practice on a breed, like answering a question on akitas if I don't quite remember what height or weight they should be. Mostly I've spent so much time in my life reading about dogs that the answer is in my head but sometimes I'm a bit rusty. They have a lot of non-US breeds and info, but also a lot of byb info. Sometimes, however, you do want to look up about a mix to know a little about them too. Even though I'm against designer dogs, I do like to keep up with them so I'm not in the blue about what different people are doing with dogs, if that makes sense to you. You can hate something and be ignorant about it, or hate it and have knowledge about it. Which is better?
