A Mastador puppy from a reputable breeder generally costs between $800 and $2,000 USD, though prices can vary.
Puppies are priced on an individual basis with prices typically between $2,500 and $4,000.
The "million-dollar dog breed" most famously associated with record-breaking sales is the Tibetan Mastiff, with individual puppies selling for over $1.5 million and even nearing $2 million in China as status symbols, though regular prices are lower. More recently, a unique wolfdog hybrid, Cadabomb Okami (Caucasian Shepherd/Wolf), reportedly sold for $5.7 million in 2025 due to extreme rarity, but the Tibetan Mastiff remains the iconic symbol of luxury dog ownership, driven by its lion-like appearance and ancient lineage.
Mastador Temperament
These large to giant-sized dogs are generally friendly and gentle towards strangers and other animals as well, but proper socialization and early training will help to fully cement these tendencies and to prevent any shyness, timidity, or aggressiveness from taking root.
Health & Lifespan
Just like in the case of people, quality of diet and healthcare are major factors. Let me start out by saying that if you do everything right in that regard, there is no reason why your Mastador should not live 13+ years.
They are fun loving, gentle giants that are highly intelligent, and sweet natured. They enjoy close companionship, are very loyal, and make wonderful companions for families or singles. Labrador Retrievers have an enduring reputation for gentle temperament, ease of handling and training, intelligence and loyalty.
The leading causes of death in Border Collies are often cancer, old age, and cerebral vascular afflictions (like strokes or aneurysms), with cancer being a significant factor, especially as the dogs age. Other serious conditions that can lead to premature death include epilepsy, heart disease (like Patent Ductus Arteriosus), Trapped Neutrophil Syndrome (TNS), and Neuronal Ceroid Lipofuscinosis (CL) (Batten's Disease) in younger dogs, highlighting the importance of responsible breeding and genetic testing.
Health Issues
Like their parent breeds, these dogs can be prone to hip and elbow dysplasia, so regular vet check-ups and maintaining a healthy weight are crucial. Large, deep-chested canines also have a higher risk of gastric torsion, commonly known as bloat.
The "heartbreak breed" refers primarily to the Great Dane, nicknamed this due to their affectionate nature combined with a relatively short lifespan (around 7-10 years) and susceptibility to serious heart conditions like dilated cardiomyopathy (DCM), making losing them particularly difficult for their devoted owners. Other giant breeds like Irish Wolfhounds, Bernese Mountain Dogs, and Saint Bernards also face significant health challenges, including cancer and heart disease, often earning them similar sentiments from owners.
While all Border Collie mixes need exercise, mixes with inherently calmer breeds like the Bernese Mountain Dog (Borbernese), Golden Retriever, or even certain Australian Shepherds often result in a more balanced, less frenetic dog than a purebred Border Collie, with the Borbernese and Golden Retriever mixes frequently cited as calmer, affectionate family companions that retain intelligence but temper the intense energy. The specific mix and individual dog's genetics greatly influence temperament, but pairing with a naturally mellow or gentle breed tends to create calmer outcomes.
A $10,000 dog often refers to rare, purebred dogs with exceptional lineage, such as Tibetan Mastiffs, Samoyeds, Chow Chows, Löwchens, and rare French Bulldogs, where pedigree, breeder reputation, size, and unique traits drive high costs, making them status symbols or investments for elite owners. These prices reflect the rarity and specialized care these breeds demand, with some even fetching much higher prices globally.
These include:
1. Tibetan Mastiff. The Tibetan Mastiff is one of the oldest and rarest breeds, originally bred to guard livestock in the Himalayas. One of these fluffy giants once sold for nearly $2 million in China, making it the most expensive dog ever.
These dogs are protective yet affectionate family companions with big personalities and even bigger hearts. Mastadors are usually gentle, loyal, and eager to please. This makes them wonderful guard dogs as well as family pets.
Another big factor in how much does a Cane Corso cost will be the color. These dogs come in a few different color shades—black, gray, or fawn are more common colors which may fetch a lower price than those Cane Corsos that are brindle, blue, or straw colored.
According to Svartberg's data (PDF), a pinscher, a Bernese mountain dog, or an English springer spaniel might be the most disloyal since each ranks very low on playfulness, with moderate sociability.
The "10 10 10 rule" for dogs refers to two main concepts: a potty training method for puppies (10 mins outside, 10 ft space, 10 mins supervision/reward) and the 80/10/10 guideline for raw feeding (80% muscle meat, 10% bone, 10% organ), both offering structure for training or diet. Another interpretation is the 10% rule for treats, limiting them to 10% of daily calories to maintain a balanced diet, ensuring most nutrition comes from complete dog food.
Dog Breeds Most Likely to Bite
"Silent killer" in dogs usually refers to deadly diseases that progress with few early symptoms, primarily Heartworm, Hemangiosarcoma (a type of cancer), and sometimes Leptospirosis or Canine Parvovirus, all characterized by vague initial signs, rapid progression, and severe organ damage, making prevention and early detection crucial.
The "5-minute rule" for Labrador puppies suggests 5 minutes of formal exercise per month of age, up to twice daily (e.g., a 3-month-old gets 15 mins) until fully grown, to protect developing joints from overexertion, though many owners find high-energy Labs need more; it's a guideline, not a strict rule, so watch for fatigue, balance structured walks with play/training, and consider mental stimulation like scent games.
The Brazilian Mastiff was originally for farming and guarded herds from predators. The darker side of their history is that they were used for chasing slaves during the 1700s slave trade. This has caused them to be antisocial and violent in the modern day. For that reason this is one of the dogs banned in the UK.
The most difficult age for a Border Collie is typically adolescence, roughly between 6 to 18 months, characterized by hormonal changes, increased independence, fear periods, heightened sensitivity to movement, and a potential "loss of recall," making training feel like starting over, though patience and consistency are key to navigating this challenging "teenage" phase.
They should not be coddled or over fussed or allowed to spend too much time with one individual. Don't make them dependent, allow them some independence and give them some respect. They are dogs, not children or 'fur babies'.
