Dog trainer reveals the two worst-behaved dog breeds are the Cocker Spaniel and Cane Corso

A dog behaviorist has revealed the two dog breeds he sees most often in his work.

Will Atherton, from the UK, said the Cocker Spaniel and Cane Corso can develop difficult-to-control behaviors as they are often adopted for the ‘wrong reasons’ in a viral TikTok clamp.

He said cocker spaniels come from a “working” line, but pet owners adopt them as “couch potatoes” or “Instagram dogs” without realizing how much training they need.

“As a dog behaviorist, I specialize in working with dogs when things go horribly wrong,” Will said in the video.

“That’s why I see the same breeds popping up again and again, showing the same kind of negative behavior.”

He said “working line cocker spaniels” are the most mischievous four-legged friends and the “number one breed that people get for all the wrong reasons.”

“They bring this dog that was bred to do work and work in the field all day and expect it to be a couch potato, an Instagram dog,” Will explained.

“That’s why they show reactivity, barking, pulling, resource guarding, and terrible recall.”

The other dog Will sees most often is the Cane Corso, an Italian mastiff and what he calls one of his “personal favorite dog breeds in the world.”

“Again, people get them for the wrong reason without the required time, dedication or experience that leads to them having a bad reputation as aggressively responsive dogs,” he said.

Research recently revealed which dog breed is the smartest and two of Australia’s most beloved dog breeds scored surprisingly low.

The Border Collie has long been considered the smartest dog in the world, but a recent one study of the University of Helsinki in Finland discovered that it is actually the Belgian Shepherd Malinois.

More than 1,000 dogs of 13 different breeds were subjected to rigorous intelligence tests, with the Labrador coming in ninth place and the Golden Retriever in last place.

Study author Dr. Katriina Tiira told The Telegraph one variety stood out from the rest during testing.

“The Belgian Shepherd Malinois stood out in many of the cognitive tasks, with very good results in most tests,” she said.

Belgian Malinois are popular choices for people looking for a dog to be a good sniffer, guard or police dog, but they also proved themselves to be independent, good problem solvers, quick to respond and good at reading people.

Border Collies proved their cleverness and performed superbly in the trials, but the Belgian Shepherd Malinois shot them on the post.

Saara Junttila, author of the study and a doctoral candidate in canine cognition at the University of Helsinki, said most of the breeds studied had their own strengths and weaknesses.

“For example, the Labrador Retriever was very good at reading human gestures, but not so good at solving spatial problems,” she said.

“Some breeds, such as the Shetland Sheepdog, scored fairly evenly in almost all tests, meaning they didn’t score very high or very low on any of the tests.”

One of the dogs’ tasks of presenting them with two food bowls, one full and one empty, to see if they could identify which one was empty was unsuccessful as there was no difference in behavior between any breed.

However, three tasks measuring a specific aspect of canine cognition were more telling, including one that required the subjects to navigate their way around a V-shaped fence.

Of the 39 potential points, Hovawarts (left) was a close third behind the Border Collie with 25 points, and the Spanish Water Dog (right) was one point away with 24 points.

Another presented the animals with an “unsolvable task” — food in a box that couldn’t be opened — to see how quickly they would seek a human for help, to determine how independent they were.

The third measured how the dogs could read people and assessed how they responded to five gestures: constant pointing, brief pointing, foot pointing, pointing at something while looking in a different direction, and following a gaze.

The Belgian Malinois came out on top for both the human gestures and the V-shaped fence tasks, scoring 35 of 39 points beating the second-placed Border Collie who scored 26 points.

Hovawarts, an old German working breed descended from the Newfoundland and Leonberger, was a close third with 25 points and the Spanish Water Dog was one point behind with 24.

The beloved Labrador and Golden Retriever scored well on the gesture test but fell behind the other two tasks coming in ninth and 13th respectively.
