Wow, a long line of relatives. Okay, let me see if i got it right this time... Your brother's pet gave birth to your daughter's pet, and your daughter's pet also gave birth to your lovely pet Kira? i hope i got it right 😊.
Your are right in saying here eyes speak for themselves. I do not own a dog, but from my experiences gathered around dogs, i can say that they make expressions with their eyes, and it means so much. It's awesome that you learnt from Kira.
Good luck my friend
