We have a (just) 10 week old femal pup. She is up to date on all vaccinations and worming with a full exam from Pilchuck Vet. Clinic pronouncing her very healthy. Her Mom and Dad are on site. She crates very well at night. She possessess all of the intelligent traits that a collie is known for, but her personality is toned down a little by the heeler in her. A very good pup. Please read about border collies.
