Hi, We have a 12 week old pup. (got her at 9 weeks). Maya is a tri-colour. We are very happy with her. She's a bundle of energy and fun. Don't know what else to say right now but hope to get to know some other people and read lots of advice.
@elbrant That's how all my 8-some learned to catch.
If food dropped on the floor - you lost it ! So they all stood on their hind legs and it was like feeding a nest of fledgling sparrows. A gentle toss of the treat and someone caught it !
Welcome to the forum.
I think Lark is a lovely name. Whatever she is you love her so it doesn't really matter. She looks a very interesting mix.
She obviously needs quite a bit of attention given to her training.
Lots of dogs don't get on with cats but with Basenjis it's easier when they grow up with them - it'll probably be harder work at Lark's age.
Work especially hard on stopping the nipping as somebody could get hurt. Try to make sure you don't get her over excited - be calm around her and she'll learn to be calm around you.
