Dogs are wonderful companions, but there're some breeds(品种) more challenging to live with and to train. Some breeds are not the best choices for new trainers or owners.

However, if you compare the numerous breeds which are more difficult to train,you'll find differences of opinion, probably based on individual experiences with individual dogs. It's im?portant to remember differences in individual dogs. If you're a novice owner or trainer,talk to a good breeder or trainer. You may need to adjust your choice of dog or adjust your training meth?od. Here,re a few other points to consider：

High-energy dogs can be a training challenge, especially if they don't have sufficient op?portunity to burn off that energy before training sessions.

Don't assume that a dog is dumb just because they're a challenge to train. If you find the

right method and if you're realistic in setting your training goals, most dogs will be more than willing to learn,although it may take some longer to learn than others. Listing a particular breed as being difficult to train may lead owners to assume that their dog can't be trained or that their dog is somehow less intelligent.

Some breeds were bred to work independently，and may not be interested in a lot of inter?action with their owners.

Other breeds are so highly tuned into their particular skill that at times it's very hard for them to focus on anything else.

Dogs bred to be vocal―guard dogs，dachshunds or hunting hounds―will be more difficult to be taught that barking is unacceptable.

Finally，any dog breed can be a challenge to train if you are attempting to train for some?thing other than what they were bred to do or that they are physically able to do. Pugs and Bull?dogs probably won't do well with scent(嗅觉) work―their noses and brains aren't wired that way. Working dogs need jobs to do or you will never train them to stop destroying the house if you leave them for hours at a time. Don't adopt a dog simply because you like the breed;mak?ing sure your dog won't be a challenge to live with and to train is as much about selecting the right breed and the right individual for you,your lifestyle and training abilities.
