The Kennel Club has said that positive reinforcement, such as rewarding good behaviour with a dog food treat, is the best method of training a dog.
It issued a letter to The One Show after Jordan Shelley appeared on programme using dominance-based techniques to train dogs.
Caroline Kisko, Kennel Club secretary, said: "The methods used were potentially counterproductive and may have caused unnecessary distress to the dog concerned. There is also a very real concern that it will encourage copycat behaviour at home that may result in dog owner injury and harm.
"The Kennel Club encourages the use of positive reinforcement training wherever possible."
She added that positive reinforcement is effective, a positive experience for both owner and dog and produces long lasting results.
According to the Daily Mail, since the show aired on Friday (September 16th), the BBC has received over 400 complaints about the segment.
In one part of the show, Mr Shelly was seen kicking dog food away from the animal as it was eating, then putting his foot into the animals mouth in a bid to show who was in charge.
