Thanks for your explanation and giving them a second chance:)!

I've to rescues myself. Farah, the last one, a Portugese Podengo, is with us for two months now. About 4 years old and she spent 3 of them in a Spanish shelter. The poor girl isn't used to anything....very shy and anxious towards people.

To provide additional answers:

1. It is wonderfull to see your foster relax and becoming a dog again. Nothing is more rewarding than seeing him/her run and play on the beach, roling in the grass etc......
2. Dogs, in this case an anxious foster, is a good example for us humans. The strengt they show, their adaptability to new environments and new conditions and their blind trust they will put into you once they trust you......

I would recommend anyone to go for adoption instead of breeder. Why? Even if the above reasons and the ones mentioned by @thebrewster are not relevant to you.......think of what kind of dog you want.....sexe, age, height, colours, charachter etc....and he/she is already alive and living in captivity. Save him / her! Most rewarding thing you will ever do, and more important, he/she gets her second chance!
Keep up the good work @thebrewster!
