so my Maltese is 16 years old and he has gone full on crazy. He is now partially blind, deaf, and has no teeth. However, we won’t put him down because he will still run happily in the yard on a sunny day like a little puppy. Now to the senile part. He will randomly bark at shadows (which instantly makes me think GHOST), he walks in circles, he walks straight off the bed, and stares into space. No matter the impairments his old age has brought him my little sammy is one heck of a snuggle buddy.
