My dog DORA (use of past participle)

 I have had a dog called Dora since 2004. She's already nine years old, which means 63 years old according animals age and 9 years old according human age. I have bought her because my mother liked the animals, especially the race Boxer. I have walked with her every day: one time in the morning and other at the night. I have gone around my village for one or two hours. I haven't learnt to walk with her without strap yet. I have put food her every day since 2003, wich means She has eatten animal food all her live. Now, for finish this description I put a photo of my dog: DORA.
