Description
This puppy exhibits the classic proportions of a Jack Russell Terrier including the distinctive V-shaped button ears and compact muzzle. The heavy ticking (spotting) on the muzzle suggests it may be crossed with a cattle dog or similar working breed. It is a sturdy, agile, and expressive little dog that radiates alertness.
Key Features
Folded V-shaped ears, heavy ticking on white fur, sharp and focused dark eyes, and a square, athletic build.
Coat Type
Short, smooth or broken coat; dense and weather-resistant with moderate shedding.
Coat Colors
White with tan, brown, and black markings; visible heavy ticking on the muzzle (freckling) that may suggest Heeler or Spaniel mix.
Temperament
High-spirited, energetic, bold, and intelligent. Likely athletic with a strong prey drive and highly inquisitive nature.
Good with Children
Good with older children; can be reactive to rough handling or high-pitched play from toddlers.
Good with Other Dogs
Fair; can be scrappy or assertive with other dogs, benefiting greatly from early socialization.
Grooming Needs
Low; weekly brushing to manage shedding and occasional baths. Regular nail trims and ear checks are essential.
Exercise Requirements
60-90 minutes daily; enjoys fetch, hiking, agility, and games that stimulate their natural hunting instincts.
Health Considerations
Patellar luxation, deafness, and eye issues like Primary Lens Luxation (PLL). Ticked mixes should be screened for hip dysplasia.
Living Conditions
Adaptable to apartments if exercised heavily, but ideal for homes with a fenced yard. Not suited for long periods of isolation.
History & Origin
Rooted in the 1800s English hunting traditions, these dogs were bred to bolt foxes from dens. This specific mix takes those hunting roots and likely adds the grit or herding instincts of another working breed.
