We also have a possible Basenji/Terrier (Yorkie) mix. I've had some doubts, but seeing this picture of Rosie, I can't help but see my Rebel. Such a great looking dog, and if she's anything like our girl, you're in for a treat!
What a cutie, sad such beautiful dogs get put down. To me the ears look Basenji and some of the things he does as well, Kaiser does a wait and stare. Do let us know if you get him tested what the results are. Find Kaiser needs mental exercise more than physical, he is a very good puzzle solver, maybe you can play some mental games and see if that helps to tire him.
I agree with the others that although he seems to have Basenji in him - his head is def. not Basenji.
As for the leg I'd have it amputated if it troubles him - He'll cope with 3 legs I'm sure, but certainly consult a specialist first. Please keep us updated.
lol yea most basenji's are actually yodelers i was just messing with the harmonica one time and she came up to me and sat down next to me and started to sing. The spoon was funny it happened once and it was her way of telling us that she hasnt been fed. When she grabbed the spoon im asking my mom maybe shes hungry? and my mom says oh right she hasnt been fed yet, she didnt want to give back the spoon though
