Lump on My Dog: When to Worry and When to Wait

The Bullmastiff was developed in 19th-century England by crossing Bulldogs with Mastiffs — the goal was a powerful, silent guardian capable of tracking and pinning poachers on large estates without mauling them. Standing 24–27 inches tall and weighing 100–130 pounds, the Bullmastiff is a massive, muscular dog with a broad head, dark muzzle, and an imposing physical presence. Their short, dense coat comes in fawn, red, or brindle — always with a black mask — and sheds moderately with minimal grooming requirements.
Bullmastiffs are confident, loyal, and naturally protective — they are alert guardians who rely on their size and intimidating presence rather than excessive barking to deter intruders. Despite their imposing appearance, they are gentle and affectionate with their families, showing particular patience and tenderness with children. They are typically calm and quiet indoors, content to lie at their owner's feet, but they can be territorial with unfamiliar dogs and require early, consistent socialization.

52About the Shih Tzu The Shih Tzu — meaning "lion dog" in Mandarin — was bred for centuries within the walls of the Chinese imperial palace, likely from crosses between the Lhasa Apso and the Pekingese. These small, sturdy dogs stand 9 to 10.5 inches tall and weigh 9 to 16 pounds, with a slightly longer body than they are tall and a proud, flowing gait. Their luxurious double coat grows continuously and can reach floor length, coming in virtually every color and combination, with a distinctive chrysanthemum-like pattern on the face where hair grows in all directions. Temperament & Personality Shih Tzus are affectionate, outgoing, and delightfully playful — bred solely as companion dogs, they have centuries of experience perfecting the art of being a devoted lapdog. They are friendly with nearly everyone, including children, strangers, and other pets, making them one of the most sociable toy breeds available.

27About 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.

14About the Vizsla The Vizsla is Hungary's national dog, with origins tracing back over 1,000 years to the Magyar tribes who settled the Carpathian Basin and needed a versatile pointer-retriever for the plains. These lean, athletic dogs stand 21 to 24 inches tall and weigh 44 to 60 pounds, with a distinctively sleek, muscular build and an elegant, ground-covering gait. Their short, smooth coat comes exclusively in various shades of golden rust — from sandy gold to deep russet — with no undercoat, giving them a clean, low-maintenance appearance. Temperament & Personality Vizslas are affectionate, energetic, and extraordinarily people-oriented — often called "Velcro dogs" because they want to be in constant physical contact with their owners. They are gentle and patient with children, friendly with other dogs, and possess a sensitivity that makes them responsive to their family's moods. Vizslas form such intense bonds that they can suffer severe separation anxiety if left alone regularly — they truly need to be included in daily family life. Pros Exceptionally affectionate and forms deep, devoted bonds with familyVersatile athlete — excels in hunting, agility, dock diving, and trackingLow-maintenance coat with minimal shedding and no doggy odorGentle, sensitive nature makes them excellent therapy dogs Cons Severe separation anxiety — cannot tolerate being left alone for long periodsExtremely high exercise needs — requires 1 to 2 hours of vigorous activity dailyProne to epilepsy, hip dysplasia, and lymphosarcomaThin coat and low body fat make them uncomfortable in cold weather If you want a devoted, athletic companion who'll never leave your side, find your Vizsla on Puplister.

27About the Treeing Walker Coonhound The Treeing Walker Coonhound was developed in the United States from Walker Foxhounds in the mid-20th century, selectively bred for their exceptional ability to trail game and "tree" raccoons by chasing them up a tree and baying until the hunter arrives. These elegant, athletic hounds stand 20 to 27 inches tall and weigh 50 to 70 pounds, with a lean, muscular build and the classic tricolor pattern — white, black, and tan — reminiscent of their foxhound ancestry. Their short, smooth coat is dense and protective, well-suited for long hours working through brush and rough terrain. Temperament & Personality Treeing Walker Coonhounds are confident, intelligent, and affable — possessing a friendly, sociable nature that makes them enjoyable companions both in the field and at home. They are gentle with children, typically welcoming to strangers, and usually get along well with other dogs, especially those they've been raised with. Their hunting instincts run deep, however, and they can switch from couch potato to tireless tracker the moment an interesting scent crosses their path. Pros Friendly, easygoing temperament — excellent with families and other dogsLow-maintenance coat needing only weekly brushingSuperb endurance for hiking, running, and outdoor adventuresGenerally healthy breed with a lifespan of 12 to 13 years Cons Extremely vocal — loud baying and howling are a defining breed traitPowerful scent drive makes off-leash reliability very challengingRequires substantial daily exercise — bored Walkers can be destructiveProne to ear infections and hip dysplasia Treeing Walker Coonhounds bring athletic grace and a sweet disposition to any home — explore available listings on Puplister.
