I have a large chihuahua as well - he is 12 pounds at 5 years old. When I got him I thought he was going to be a purse dog lol. I have seen them in all sizes. Whenever we go to the dog park I get "wow that's a big chihuahua" but I love him just the way he is
"He is your friend, your partner, your defender, your dog. You are his life, his love, his leader.
He will be yours, faithful and true, to the last beat of his heart. You owe it to him to be worthy of such devotion."
