Working-line Border Collie from an exceptionally concentrated Int Sup Ch pedigree. Progeny profile and specific working record available on request; Kate keeps a full record of every pup produced from her line.

Progeny of Dallas are competing successfully at agility across the UK. Kate describes them as "totally rounded progeny" — an early indicator of the working sport dog Dallas's concentrated Int Sup Ch pedigree produces. Dallas shares the Belle dam line with a Rippletrix bitch whose own pups have excelled in both working sheepdog and agility disciplines, giving a strong indication of the family line's consistency across generations. Every pup produced from Dallas is fully health tested to the recognised working-Border-Collie panel (hips, elbows, eyes, CEA, TNS, CL, MDR1, IGS). Kate keeps a full record of every pup produced from her line; specific progeny details available on request direct from the kennel.

Full BVA hip and elbow scoring, annual eye certification, and DNA panel screening across the recognised working-Border-Collie panel (CEA, TNS, CL, MDR1, IGS) held on file. Specific scores displayed on the Kennel Club register under registration AZO915278 and via the ISDS register under OO/374768. As a Veterinary Physiotherapist Kate assesses puppies for orthopaedic soundness at the point of leaving her yard.
