No, not ALL his dogs, but a lot.
Orson was pts after not doing what he should have for the dog imo, Homer was rehomed, What happened to Devon, Emma, Clementine, Pearl....? According to his site he only has 3 dogs now- Lenore, Izzy, and Rose. But then again, hasn't he sold the farm since then so I'm not even sure that's current.
Does anyone have a full list of his dogs and what happened to all of them? Maybe they were all bad fits... I don't know. But something is wrong if you have that many problems with that many dogs in such a short time. Perhaps it was the wrong breed, though not all were bcs. If so, then he should take a real, serious look at the type of dog he's bringing home because he's obviously not understanding them. He seems to me to simply use his dogs to further himself.
ETA:
I could find a more isolated and peaceful home for him, where fewer people visited to alarm him.
Wasn't the farm like... 99 acres?
