Lopez was adopted because he looks like a cross between ou two dogs who had died in the past 2 years. Buddy had lived till 19 and a half and Sy Sy until at least 17. Lopez was older, too, but quite vibrant and fun. Within 6 months, he was showing signs of canine cognitive disorder. 2 & 1/2 years later, we now have a dog with Alzheimer's. It's a good thing he's so sweet and full of love or he would drive me completely insane. Dogs. Gotta love em.
