Rhett is a 6 month old, 24lb terrier mix who is ADORABLE!! He is super dog friendly and is unsure of the kitty cats. Rhett is just a plain ol' typical puppy! He should be a medium guy when he's full grown as he is growing rapidly! He is full of playful spunk and his foster reports that although he has plenty of puppy energy he is VERY smart and attentive, learning fast and retaining what he learns. He is currently working on his potty training and leash manners.
