Cody's beautiful! Love this pic with the kitty on the other side. My prayers are with you and Cody for a baroooootiful union.
Please keep in mind that using training treats of very high value is a key to success. Good advice I received about this breed is: (addressed to me)
Breeds like jacks and basenjis have a different value system - they work for themselves, not for us. If they decide to do something for us, it is because the value of the reward means more than the task being asked - unlike other breeds that will work for us because they want to please us; your combination of breeds is only interested in what pleases itself. Understanding that can go a long way with training.
My boy Duke is a basenji-mix (1yr 4 mos old), I think with jack russell. In all . . a really big handful in his puppy time, 4 mos. before I knew what the heck he was. Today? Ahhhhhhh - he is my true baby love. Training him how he needed to be trained saved face for me and him. He is my loyal subject - with big wings that Daisy must trail. She is only 4 mos old, in training. She has another personality and we have some training problems, but I am more prepared than before. Big treat rewards . . . cheese, bacon, steak, corned beef. Yeah - I believe in spoiling a li'l.
