Its my personal belief that all people that shop online for dogs do not have the dogs best interests in mind. Especially when the tag line of the website is "find your dog for free!"
If you can't afford the dog, or are unwilling to travel to rescue areas or shelters to make personal face-to-face interactions with the people, and PAY for the dog, you don't need a dog. (I understand not driving to a rescue in California if you live in Kentucky, or circumstances like that)
I drove well over 400 miles in my search for my newest addition.
Real breeders that are genuine and have worth-while puppies do not need to advertise online. They have a waiting list.
Most ads have decoders to them too.
"Weary of strangers" Will bite.
"Great with kids" Good with OUR kids.
"Enthusiastic" We can't train him.
"Loves exercise" Escapes the yard often.
"Great guard dog" HAS bitten.
I'll add more as I see them.
