Bernardo was very lazy and slept basically all the time at first. Now, at 15 weeks of age, he still sleeps a lot but has a lot more energy, and he is a lot more vocal. This little pup has something to say about everything. He barks, whines, groans, sighs, and is, in general, a super funny guy. My friend has a sister of his from the same litter and they absolutely adore each other. When we have them together they play nonstop but when it's time to go to bed they are the best of cuddle buddies.
