About Venomline Pocket Bullies
Venomline Pocket Bullies is a production-focused Pocket American Bully program founded by Matt Siebenthal. Built from the legacy of Louis V Line’s Venom and developed through multiple generations, Venomline selects for compact proportions, recognizable breed type, functional structure, stable temperament and traits that can be verified through mature offspring—not marketing alone.

Our story
From Texas Size Bullies to the Venomline Bloodline
Venomline’s history began before the current name. The breeding program developed from Texas Size Bullies and later evolved into Venomline Pocket Bullies—a name created to honor the influence of foundation sire Louis V Line’s Venom, known as “Chunk.”
Venom was more than the face of the program. His compact frame, head type, bone, presence and companion temperament became a reference point for what Venomline wanted to preserve and reproduce. The goal was never to create one famous dog. It was to develop a recognizable family of dogs that could carry desirable traits into future generations.
That work continued through Venomline-owned productions, proven outside studs, daughters, sons, grandsons and carefully selected females. The result is a breeding identity that can be evaluated through the program’s documented production portfolio and independent client litters.
Founder
Matt Siebenthal and the Venomline Standard
Matt Siebenthal founded Venomline around a breeder’s central responsibility: make deliberate selections, document the results and remain accountable for what the program produces. That standard requires more than promoting a pedigree or a carefully staged photograph. It requires evaluating dogs in natural stance, in motion, at maturity and across different pairings.
Venomline’s public content, videos, production archives and client-litter records are intended to let buyers and breeders review the program critically. Where stronger documentation becomes available, the record should become more specific—not more exaggerated.
Bloodline identity
What the Venomline Bloodline Is Designed to Produce
The About page does not replace individual stud profiles, breed guides or production records. Its purpose is to define the traits Venomline consistently prioritizes and explain how the program evaluates them.
Compact, recognizable breed type
Shorter, balanced proportions; substantial bone; broad fronts; strong head type; and an unmistakable American Bully outline without treating size alone as quality.
Functional structure and movement
Feet, fronts, rears, toplines, proportions and natural movement matter because extreme traits should be supported by a functional foundation.
Stable companion temperament
Confidence, manageability, affection and the ability to live safely in a family environment remain essential traits in a powerful companion breed.
Repeatable production
Venomline evaluates whether desirable traits appear across different females, litters and generations rather than relying on one isolated result.
Proof before promises
How to Evaluate Venomline
No breeder should be judged by claims alone. Venomline encourages buyers and breeders to review the same evidence used to evaluate any established breeding program:
- Named dogs with identifiable sire and dam information
- Mature photographs and natural movement where available
- ABKC titles described accurately and conservatively
- Results across multiple females, litters and generations
- Independent client litters—not only in-house productions
- Clear current terms before a puppy reservation or stud booking
Start with Pocket Bullies Produced by Venomline, then compare those results with the Client Litters archive.
Temperament and daily life
Family-Raised Dogs, Not a Kennel-Only Product
Venomline dogs are raised with regular handling, household interaction and real-life exposure because temperament develops through both genetics and environment. The goal is a dog with enough presence to represent the breed and enough stability to live as a dependable companion.
Breed type should never be used as an excuse to ignore breathing, movement, behavior or quality of life. Venomline’s stated direction is to build extreme visual traits on top of structure, function and stable temperament—not in place of them.

Recognition and reach
A Bloodline Recognized Beyond One Generation
Venomline dogs and program history have appeared in bully-culture media, mainstream features and video coverage. The more important measure, however, is the program’s continued production across owners, regions and generations.
Venomline’s current production portfolio documents more than 50 ABKC Champions and more than 20 Grand Champions. Those aggregate figures should remain supported by named examples, parentage and title documentation as the archive continues to improve.
