I assume pets meaning animals, but the smile and grin confuse me to a benevolent agenda..
...I do have a great old lady, she is the love of my life, she is a 19 year old yellow Labrador named Nana. I have had her since I was 6. She still walks fine and all, she just has some arthritis in her back hips and she cant hear anymore. I have to gesture to her with shadows and then she sees me. Here is a picture, this is her smiling after she saw me waving to her. She has a pink nose from licking all the pigment off. She is my princess...I did also have a Welsh Corgi Pembroke named Peri. He lived till he was 15. I do not know how my puppies lived so long, but we used Iams Green bag, walked once a day, and no table scraps unless they were raw vegetables during prep. IF any of you are in AZ we use Southwest Pet Clinic with Dr. Lee in Tucson, the doggy fountain of youth...
