My parents have a part Rhodesian Ridgeback. Shes a mutt, but she basically looks like a smaller version of the RR.
She is insanely loyal to us, and loves to play ball. One of our favorite tricks about her was that she could open all the doors in the house. Became quite a pain in the ass, but once the doggie door was put in, she used it just fine. Is very wary of strangers, but never bit anyone or acted out. She always listened to us, but we made sure to train her right from the beginning. Like everyone says, they are insatiable when it would come to exercise. I could run 3 miles with the dog and she wouldn't even be tired! She is the independent alpha dog of the house, but she loves to cuddle when she is tired. She is seriously obsessed with her red ball!
I dont get to play with her as much as I used to, but every time I go home I always make sure to play some ball. Shes about 6 years old now, and I can finally tire her out with excercise! It takes about 30 minutes of throwing it, but as of a couple weeks ago I have finally been able to get her to quit. She NEVER did it before in the 5+ years I have played ball with her.
Overall: great dog, doesnt shed much, very loyal to owners, always listened to our commands. Was the alpha dog of the house and keeps the other 2 dogs (Shiba-Inu(I think) and Mini Dachshund) in check.
