My oldest baby, Scrappy Doo, is a MinPin-Chihuahua (16 yo) who has gone blind & deaf w/in the last 6 mon. He has developed allergies, is very sweet & still has bouts of playfulness. He weighs 8. 5 lbs., likes to burrow, & sleeps most of the day. He MUST be on a leash outside for his safety.
My other baby is a Schnoodle who is about 13 yo, who is the biggest lover in the world, (should have named him Casanova!) He weighs about 20 lbs,, loves belly scratches & snacks!! He walks well on a leash, but also loves to run free in a fenced yard. He plays well with people, but does get a little timid around new dogs. He likes them, it takes a little bit to "trust" them, so it's best to keep him on a leash until trust is gained. He came around to my son's pit bull and his Chihuahua ... it just took time.
