More: This boy is the sweetest! Everyone loves Tyler. And he is a 16 year old! He still looks like a puppy! He acts more like a bunny then a terrier. He is so laid back and everyone loves him. He was very sick as a puppy with pneumonia, but he managed to pull through. He is a very strong boy even though he’s the mushiest dog I’ve ever met! He’s my little bestie. Senior dogs are amazing! They should be celebrated!
