Found a lump on your dog? Learn when to worry and when to wait for a lump on my dog, especially for adopted pets with unknown histories.
The Australian Cattle Dog — also known as the Blue Heeler or Red Heeler — was developed in 19th-century Australia by crossing native Dingoes with Collies and Dalmatians to create the ultimate cattle-herding dog. Compact and muscular, they stand 17–20 inches tall and weigh 35–50 pounds, with a sturdy build designed for all-day work in harsh outback conditions. Their distinctive short double coat comes in two color patterns — blue or blue-mottled and red speckled — and sheds moderately year-round.
Australian Cattle Dogs are intensely loyal, highly intelligent, and tireless workers — they need a job to do or they will invent one, often to their owner's dismay. They bond deeply with one person and can be velcro dogs, following their favorite human everywhere. They are naturally cautious with strangers and may nip at heels — a herding instinct that needs to be redirected — but they are fiercely devoted companions for active owners.

22About the Shiba Inu The Shiba Inu is Japan's oldest and smallest native breed, originally bred to flush birds and small game in the dense mountain underbrush — "shiba" may refer to brushwood or the breed's red color, while "inu" simply means dog. These compact, agile dogs stand 13.5 to 16.5 inches tall and weigh 17 to 23 pounds, with a fox-like face, small triangular ears, and a curled tail. Their stiff, plush double coat comes in red, sesame, black and tan, or cream, with distinctive "urajiro" (cream to white ventral markings). Temperament & Personality Shiba Inus are bold, alert, and fiercely independent — often described as more cat-like than dog-like in their self-possession and fastidious grooming habits. They are loyal to their families but on their own terms, and their strong-willed nature means they do not blindly follow commands. Shibas are known for the infamous "Shiba scream" — a loud, distinctive vocalization produced when displeased or overjoyed — and they can be aloof with strangers and sometimes aggressive toward other dogs. Pros Naturally clean and almost cat-like — easy to housetrain and self-groomingCompact, manageable size for apartments with adequate exerciseLoyal and devoted to their family once trust is establishedHealthy breed with a long lifespan of 13 to 16 years Cons Extremely independent and stubborn — not recommended for first-time ownersStrong prey drive and unreliable recall make off-leash freedom riskyCan be possessive of food, toys, and territory (resource guarding)Prone to allergies, patellar luxation, and hip dysplasia The Shiba Inu's spirited independence and striking looks have won fans worldwide — discover Shibas on Puplister.

15About the Shetland Sheepdog The Shetland Sheepdog — or "Sheltie" — was developed on Scotland's remote Shetland Islands, where harsh conditions favored smaller, efficient herding dogs that could thrive on limited resources. Standing 13 to 16 inches tall and weighing 15 to 25 pounds, Shelties resemble a miniature Rough Collie but are a distinct breed with their own standard and lineage. Their abundant double coat features a long, straight outer layer and dense undercoat, coming in sable, black, and blue merle — all typically with white and tan markings. Temperament & Personality Shetland Sheepdogs are incredibly intelligent, sensitive, and eager to please — consistently ranked among the top 10 most trainable dog breeds in the world. They are devoted to their families and particularly gentle with children, often forming an especially strong bond with one household member. Shelties can be reserved with strangers and may bark to alert their family, but their sensitivity and willingness to learn make them wonderful companions for patient, attentive owners. Pros Exceptionally intelligent — excels in agility, obedience, and herding competitionsGentle, affectionate, and outstanding with childrenCompact size with all the beauty and grace of a CollieLoyal and deeply bonded to their family Cons Heavy shedding — the dense double coat requires frequent brushing and sheds year-roundProne to excessive barking, especially when excited or alertingSusceptible to Collie eye anomaly, hip dysplasia, and dermatomyositisCan be timid and fearful without proper early socialization Shelties combine beauty, brains, and devotion in one elegant package — explore Shetland Sheepdog adoption options on Puplister.

46About the Staffordshire Bull Terrier The Staffordshire Bull Terrier was developed in 19th-century England's Staffordshire region from crosses between Bulldogs and various terriers, originally bred for bull-baiting and later as a compact, agile fighting dog — a history that belies its true nature as a devoted family companion. These muscular, athletic dogs stand 14 to 16 inches tall and weigh 24 to 38 pounds, packed with surprising strength and agility in a compact frame. Their smooth, short coat comes in red, fawn, white, black, blue, or brindle — with or without white markings. Temperament & Personality Staffordshire Bull Terriers are affectionate, courageous, and remarkably gentle with people — earning the nickname "nanny dog" in England for their extraordinary patience and devotion to children. They adore human companionship, are playful well into adulthood, and form intensely loyal bonds with their families. While they can be assertive with other dogs, proper socialization from puppyhood typically produces a confident, well-adjusted adult that gets along with everyone. Pros Exceptionally affectionate and gentle with children and family membersCompact, muscular build well-suited for smaller homes and apartmentsLow-maintenance coat requiring only occasional brushingBrave and loyal — a devoted companion that thrives on human interaction Cons Can be dog-aggressive without careful socialization and managementBreed-specific legislation and housing restrictions in many jurisdictionsProne to hip and elbow dysplasia, L-2 hydroxyglutaric aciduria, and cataractsStrong and powerful — requires owners who can provide firm, consistent leadership Staffies are among the most devoted family dogs in existence — find a Staffordshire Bull Terrier on Puplister and see for yourself.

17About the Whippet The Whippet was developed in Victorian England by coal miners and mill workers who bred small Greyhounds with terriers to create an affordable racing and rabbit-coursing dog — earning the nickname "the poor man's racehorse." These elegant sighthounds stand 18 to 22 inches tall and weigh 25 to 40 pounds, with a streamlined, aerodynamic build capable of reaching speeds up to 35 miles per hour. Their short, smooth coat comes in virtually any color or pattern and lies close to the body, accentuating their graceful, muscular contours. Temperament & Personality Whippets are gentle, quiet, and remarkably calm indoors — often spending hours draped elegantly across furniture in poses that would make a greyhound proud. They are affectionate and sensitive with their families, good with children (though their slender build makes them vulnerable to rough play), and generally friendly with other dogs. Despite their sprinting ability, Whippets are surprisingly low-energy at home and are often described as the ideal apartment dog for owners who enjoy outdoor exercise. Pros Extremely calm and quiet indoors — one of the most unobtrusive housematesShort, low-maintenance coat with minimal shedding and no doggy odorGentle, affectionate nature — rarely aggressive toward people or other dogsHealthy breed with a long lifespan of 12 to 15 years Cons Intense prey drive — will chase and potentially catch small animals including catsThin skin and low body fat make them sensitive to cold and prone to scrapesCannot be trusted off-leash in unfenced areas — once they run, they cannot hear youSusceptible to anesthesia sensitivity and cardiac arrhythmias Whippets are the perfect blend of couch companion and outdoor athlete — find one looking for a home on Puplister.
