Are Simba came to us first, such a wonderful dog so full of energy and always getting into mischief. He loves to run through the yard and hop and bounce he gets so high when he jumps you think he will make the fence. We brought home our Rex our puppy with the most spots last year. Rex was so small and his bed was so big and now he has out grown but still finds away to fit in his bed because he knows that it is his. Simba and Rex are the best of friends and are inseparable. They are two peas in a pod.
