Shelters and animal shelters are overcrowded. The abandonment of dogs is a very serious problem all over the world, also in Spain. Before finding a definitive family, many of these animals will pass through a foster home, but You know that they are?
Animal shelters are essential in the adoption process. It is the fastest way to give those furry a chance, taking them out of the cage and taking them to a home where they will receive all the necessary care until someone takes an interest in them.
As we know, not all dogs are the same, nor do they, therefore, have the same character or ability to learn. Some of those who end up in shelters have been mistreated, or have not been properly socialized and therefore are afraid of dogs and / or people. And that's not to mention that there are some breeds that have a harder time finding families, such as greyhounds or hounds.
All these dogs are very vulnerable, and would be even more so if it weren't for the foster homes. If you want to welcome someone, you simply have to offer your home as a temporary foster space. You decide how long you want to host him, but the ideal is to have him until that furry finds a permanent home.

During those days, weeks or months, what you will have to do is take care of it as if it were yours; that is, you have to give him food and water, take him for a walk, play with him daily, and take him to the vet if necessary. Some Protectors take care of the expenses, but others could ask you to take care of them, at least for some (food for example). Consult them before taking in a dog.
