I found my dog, emaciated and hairless, covered in fleas and ticks, in Villa El Salvador. At just two months old, he was tiny, little bones sticking out of his itchy skin. Spotting him was fate. My wife and I both happened to turn to the right at the same time, seeing him pass slowly from under one car to the next. We confirmed with each other what we had seen, jumped out of my father in law's car and had a look around.
Just a puppy, he hadn't really learned to be wary of strangers yet. As we picked him up, a couple of girls running a small stall immediately handed me a plastic bag to take him home in. I put him in the bag and tied the top so only his head could stick out.
We took him to the vet and had him washed, deparasited and gave him his initial shots. Back at home, I carefully took off the remaining dead fleas as he fell asleep with exhaustion. It must have been a terrifying day.
A little later we took him outside. I put him down on the street and took a few steps away. He looked at me, the looked around, then looked at me, unsure what to do. He wasn't sure if I was sending him away or whether he was supposed to come with me. I crouched down and told him to come. His tail moved ever so slightly and he followed. To this day he's never more than a metre away from my feet at all times!
It took him a couple of months to get over the trauma, loose those sad eyes and learn what it meant to play.
This is Lucky now...
Don't buy a dog.
