Should you get a Bull Terrier?
The Bull Terrier is a unique dog breed that is often misunderstood. They are known for their playful and loving nature, but there is much more to these dogs than meets the eye. Here are 14 interesting facts about the Bull Terrier.

Bull Terrier Origin
The Modern Bull Terrier first emerged in England in 1862, when James Hinks introduced the breed at a dog show. Often regarded as the founder of the original Bull Terrier, Hinks was instrumental in refining the breed’s appearance and temperament. His efforts established the distinctive look and traits that define the Bull Terrier we know today.
Bull Terrier Development
While other breeds may have contributed, the Bull Terrier’s development is most commonly linked to the Bulldog, the English White Terrier, and the Dalmatian. Originally bred for 19th-century blood sports like bull-baiting and dog fighting, these dogs were later refined to temper their aggression. Over time, selective breeding transformed them into the affectionate, playful companions we recognize today.
Bull Terrier Traditional Coat Colors
In the breed’s early days, Bull Terriers were exclusively white. This changed in the early 1900s when the first colored variants appeared-a development met with resistance from purists who feared diluting the breed’s standards. For decades, controversy persisted, and it wasn’t until the 1950s that colored Bull Terriers gained full acceptance. Today, the breed proudly showcases many colors and patterns.

Bull Terriers are OCD.
Research indicates Bull Terriers and German Shepherds display significantly higher rates of compulsive tail-chasing behavior compared to other breeds (Moon-Fanelli et al., 2011). These dogs may also exhibit light/shadow chasing behaviors (Tiira et al., 2016).
A 2012 study found nutritional supplementation reduced tail-chasing frequency in affected dogs, though the precise mechanisms remain unclear (Overall & Dunham, 2012).
Key Nutritional Interventions
Tryptophan-Enhanced Diets
Study: Overall & Dunham (2012) used diets supplemented with L-tryptophan (a serotonin precursor)
Rationale: Serotonin modulation may affect obsessive-compulsive behaviors
Omega-3 Fatty Acids
Evidence: Subsequent research (e.g., Korpivaara et al., 2017) showed reduced anxiety-related behaviors with EPA/DHA supplementation
B-Complex Vitamins
Observed Effect: Some studies noted improved neurological function with methylated B12/folate

Bull Terrier Intelligence
In the Landmark Book entitled, “The Intelligence of Dogs”, professor Stanley Coren researched and documented the intelligence of over 130 different dog breeds. In his book, the Bull Terrier ranks 49th out of 138 breeds in working/obedience intelligence. Essentially this means they will learn new commands in 25 to 40 repetitions and obey first commands more than 50% of the time. This puts them in the “average working and obedience intelligence” category. In contrast, the most intelligent breeds will learn the same command in 5 repetitions or less!
