I can top it. I've got a friend and her husband that are not dog people, never have been. They seem to think that feeding them high quality food and supplements makes them good dog owners.
However, after buying a Tosa Inu and not bothering to train it at all, and it didn't automatically know what they expected of it, they dumped it down a rural road, convinced the local farmer there would love to have it as a pet. Did they ask him? Did they know him? Nope, just assumed that because they were stupid enough to pay a ridiculous amount of money for a poorly bred dog with a rare breed on it's registration papers that anyoe would know what it is, what it's worth and be glad to take it in.
Then they go and get a Dogue De Bordeaux. Again, not well known large breed dog that they paid way too much money for from a back yard breeder. Again, dog didn't know what to do, how to behave because they never trained it. So when they let their young pre-school age kids crawl all over him and pull his ears and chew on it's tail and it finally had enough and nipped one of them, they took him out back and shot him in the head.
Finally they move to another state. They apply for - and God only knows how the hell were approved - to adopt a female pit. I begged her not to adopt the dog. Told her she had no business owning a large breed dog if any at all. She thinks because her Pyr is a good dog she's a good dog owner and it's been the dog's fault all along. Gah!! Obviously a crappy rescue - or more likely she got it for free from teh local paper. Nothing I did or said would change her mind. I finally gave up and the friendship is over. Can't be around knowing the fate of that poor dog they adopted.
