Animal abuse is a global disease and is quite bad here in Spain. Some Spaniards (not all but some, especially those living in particularly rural areas) don't hold dogs and cats in a very high regard and if they are not straight up abused they are often relegated to living a life in filth with little to eat. It's not unusual to see filthy emaciated dogs tied up in yards or running loose in packs. There are stray cats everywhere, packs of them that hang out by the dumpsters.
Spain is on average pushing a 20% unemployment rate, 28% here in Andalucia, and a lot of the local governments are rife with corruption and bankruptcy. People who no longer want or can't afford their animals simply turn them loose in the streets or countryside. Municipal run "pounds" are known as little more than killing stations where dogs and cats are held for an obligatory two weeks in conditions that rival your typical mill, unfed because there are no budgets or the money has been stolen, and then are killed.
Fortunately for some there are privately run animal societies funded by people who care about animals. There are 4 or 5 that I know of within about an hour's drive of me. They aren't the doggy Ritz, but they do their best with what they have to work with. They are no kill facilities as long as they can sustain their populations and at any given time each has 200-300 dogs. Dogs are available for adoption and most every dog owner we know has a "rescue" dog or two. Unfortunately a lot of Spaniards prefer instead to get pure breed puppy mill dogs from the pet store at €300-€500 a piece and spaying and neutering isn't as common here as it is in NA.
We rescued a dog lying in the street that had been hit by a car. One of the local societies paid the €300 for it to have a pin put in a broken leg and it was then adopted out by some friends of ours.
Speaking about breed specific shelters, Greyhound and Whippet racing dogs come to mind, and here in Spain there are several that specifically take in Podencos (Ibizan Hound), a Spanish hunting dog. It's a really neat breed of dog.

I've told this story before but whatever. My girlfriend and her friend were walking her friend's dogs when another one came out of a dirt lot full of donkeys and goats. She had a wooden crate in the middle of a dry sunbaked lot with no shelter from the elements. She squeezed out under the fence to see them. She had a piece of twine tied around her neck that she was growing into, was a rack of bones, and was covered in about 200 ticks.
The girls went home and got a bag of kibble and scissors and went back to feed it and cut the string off. It followed them home and I got a call at work to see if she could have a dog

Funny enough, a couple days later while walking her an old man gave my girlfriend supreme shit for not feeding her properly! She cleaned up nicely and has since turned into an 80lb sweetheart. She's now 4.
So yeah, I'm nearly flat ass broke right now with every cent tied up in my projects, but I would be happy to help other ways, server space or design for example. We've donated several times in the past to the SPCA in Canada. I'd sooner give to animal charities that human handout ones, save for those that support people with mental health or medical issues, because I'm a firm believer that people are perfectly capable of helping themselves and animals aren't.
