Key Dates
Lineage & Genetics
Both parents Embark DNA tested and clear on all 15 breed-relevant genetic conditions screened, including Degenerative Myelopathy, MDR1 Drug Sensitivity, Hereditary Cataracts, Collie Eye Anomaly, and von Willebrand Disease Type I.
Because both Valli and Mack are clear, no puppy from this pairing is expected to be affected by, or to be a new carrier of, any screened condition. Each family receives full DNA results on their puppy.
MDR1 Drug Sensitivity is associated with Australian Shepherd ancestry and affects how certain medications are processed. Because both parents are clear, no puppy from this pairing can be affected. Families should still inform their veterinarian of the breed background so medication protocols can be confirmed.
Predicted litter eCOI is approximately 2%, a meaningful drop from either parent's individual COI. Lower effective COI generally correlates with hybrid vigor and long-term health.
Temperament Assessment
Tamsin was evaluated using the Volhard Puppy Aptitude Test at approximately 6 to 7 weeks of age. Scores have been translated into the Stokeshire 12-trait temperament framework to help families understand her natural disposition and identify the right home match.
About Tamsin
Tamsin carries a blue merle tricolor coat with copper-tan points and white trim. Her marbled merle pattern is balanced and softly defined.
Her temperament assessment reads as even and engaged, a steady, family-friendly profile. She settled easily under handling and stayed attentive to her surroundings, pausing to assess sound and movement with quiet awareness.
As an Australian Mountain Dog weighted toward the Australian Shepherd side, Tamsin pairs Aussie attentiveness with Bernese steadiness. A balanced profile like hers tends to settle well into active homes with structure and predictable daily engagement.

Coat & Size
What Is an Australian Mountain Dog?
The Australian Mountain Dog is a cross between the Bernese Mountain Dog and the Australian Shepherd. The pairing is designed to unite two complementary qualities: the calm, devoted temperament and substantial structure of the Bernese, and the working intelligence, trainability, and environmental engagement of the Australian Shepherd.
Unlike the Australian Mountain Doodle, the Australian Mountain Dog does not include Poodle and is unfurnished. It carries a traditional double coat that sheds seasonally, rather than the furnished, lower-shedding coat of a Doodle. Families choose the Australian Mountain Dog for the classic Mountain Dog appearance and the steadiness of the Bernese and Aussie cross, without the weekly grooming demands of a doodle coat.
This Valli x Mack litter leans toward the Australian Shepherd side, landing in a medium, athletic frame around 45 to 65 pounds. The temperament range benefits from both lines: cognitive engagement and drive from the Aussie, emotional balance and devotion from the Bernese, right-sized for active modern family life.
Next Steps
Tamsin's temperament scores are based on the Volhard Puppy Aptitude Test conducted at approximately 6 to 7 weeks of age, translated into the Stokeshire 12-trait framework. Scores reflect her first natural response and are intended to inform family matching. They are not guarantees of future behavior, trainability, or disposition.
Each puppy is an individual shaped by genetics, environment, and training. Stokeshire Designer Doodles does not guarantee temperament, adult size or weight, coat characteristics, or shedding levels. The Australian Mountain Dog is an unfurnished, shedding breed and is not represented as lower-shedding or hypoallergenic. Coat outcomes may shift with age, grooming practices, and seasonal cycles.
Families are encouraged to invest in ongoing positive-reinforcement training, socialization, and veterinary care to support their puppy's development. By selecting a Stokeshire puppy, you acknowledge and accept these terms.
