Homeless Dogs/ Shelter Dogs

I am a dog lover. Do I want to have them or not, good times or bad, I  always have a dog in my home.

I just got an interesting notes from independent journalists I am working with time to time, about homeless dogs in Bulgaria. I can't promise the best translation, but I will try to get to the point.

"I don't know exactly what type of ear ring it is...I have to talk to Bulgarians. I know for sure that all the street dogs have it. It is an electronic chip, if to take a closer look.
In the small city of Balchik or even Varnas ( what is a big city) there are a lot of dogs and cats. They are homeless in the way that they do not have the owners and live their own life. They find the food around Cafes or wherever else.
It was a surprising fact that dogs don't chase the cats. They live together in peace and walking down the streets not paying attention on each other. Probably it is because the people are nice and kind in here and the animals are the same."

Ok. Let's get back to the US Shelters. They say they spend a lot of money, and keep the animals only for 30 days (as much as I know), because they can't afford them. I understand LA is a big city, but....
The Shelter can make a new program and collect a free foods from Cafe's and Restaurants. There is a lot of meat, bones and veggies goes into the garbage from the kitchen and left overs from plates every day. People do collect the bottles from streets, why not foods for Shelters, so they can afford more workers and do not put down animals after a short period of time.
No one dog died from humans food yet, as one of my friends said. So... Just a thought.
