Pure Aussie puppies

Great working dogs! 3 females available, 2 at 12 week old and one at one year old. 12 week olds are spot trained and learning command, one year old is a farm dog (meant for outside). One may turn out red (red on dad's side, pure blue on mom's). I've had mom as my breeder for 6 years and she's never thrown a bad pup. No defects or health issues, all have shots currently. Puppies are playful and excited while the older one is true to her in breed and very standoffish with new people.
