The Borzoi or Russian Hunting Sighthound is a Russian breed of hunting dog of the sighthound type. These beautiful dogs were once used for wolf hunting, and until 1936 were known as the Russian Wolfhound.
Borzoi dogs are intelligent and very affectionate with their owners but are also independent and sometimes stubborn, so training may prove to be a challenge. Patience and consistency are key. Overall they are usually gentle, well-mannered companions.
Australian Cattle Dog
The Australian cattle dog also goes by the name “blue heeler” or “Australian heeler.” But whatever the breeder or the shelter calls him, he’s not the ideal fit for a brand-new dog owner.
They have a reputation for being stubborn and having energy to spare — not to mention a truly adventurous spirit and belief in their own invincibility that will leave you wondering how they'll injure themselves next. Additionally, Australian cattle dog owners must establish themselves as pack leader to promote a harmonious household.
Airedale Terrier
Notoriously clever and stubborn, Airedales are tricky simply because they’ve got a typical terrier temperament in a large dog body. Terriers are known for being independent thinkers and voracious predators.
While this can be cute in a Jack Russell, it can be tricky to manage with a larger breed like an Airedale. They are also quite vigilant and may be unfriendly to newcomers, which can be an additional challenge for owners who like to have guests.
Caucasian Shepherd
They may look like a cuddle buddy, but they are formidable guardians and were bred to guard anyone or anything that they deem their family.
They make excellent guards because of their strong-willed tendency, fearlessness, and independence. By nature, these shepherd dogs can be highly aggressive unless they're very well trained. They're also only really happy when they have a job to do, these dominant dogs can be a challenge even for the highly experienced dog owner.
Anatolian Shepherd Dog
Protective and territorial, but also intelligent, patient, and profoundly loyal, these muscular avengers are prized as working guard dogs without equal. Anatolian owners must be strong leaders, willing and able to handle a dog as dominating and demanding as it is calm and loving.
The Anatolian Shepherd dog was first bred to work independently, make decisions on his own, and protect his flock from outsiders, so training the breed to respond to commands will definitely be a challenge.
