This page is the puppies first seven weeks of life covering up to adoption day which will be starting Nov. 4th 2017 for the litters they have reached 7/8 weeks of age depending on just which state you live in. Va. law is 7 weeks of age NC. is 8 weeks of age. ( The two states can't agree on that issue so I'll decide what's best for me and mine, thank you. ) You really can not tell one blue merle from the other very well during the first 3 weeks. The first 1- 5 days they can not regulate their own body temperature their also not able to hear nor see for as long as 9 to 11 days after birth. Types below are blue merles, black tri, red tri, black bi, red merle, red bi. ( Bi =2 color. tri =3 color ) Someone asked me what did merle mean? Merle is the name of a gene that causes the color in skin pigment, hair color, and eye color in aussie's. Having a coat of irregular streaks = merle. They come in all shades of red, yellow, copper, tans, silver blues, grays, and they're all quite beautiful.
