Perhaps you have read this article or seen it on the news lately. i’m certainly not going to claim that it is fake news however you have to think about what’s being discussed and what the regrets are.
The creator was disgusted at puppy mills and those who do mass breedings just for profit. It wasn’t the dog or its temperament that the creator regretted.
If you are interested in a Labradoodle you should research the breed. perhaps you could talk to a neighbor or friend who has purchased one and discussed their likes and dislikes. Talk to your vet as well about them being hypoallergenic. Like most people you probably aren’t going to find many negatives about this breed.
So as a future dog owner or while you are doing research it is important to consider the personality of the dog you would like to purchase. It doesn’t matter so much about how they came into existence or what the original creator has to say
