I had a rescue before and she was not potty trained, always scared (pees when scared), nervous, etc. She had a lot of issues because she was neglected and abused. She was also from a breeder that bred her, but starved her.
First and foremost, it's rewarding to have a rescue (knowing that you saved her life), but it's also a LOT of work. I really don't think rescues are for me after my experience with her. However, when I took her in, I never thought of keeping her, I just wanted to get her in good shape and adopt her out. If I were to really pick a rescue to adopt as my own, I would have put more factors into consideration. I probably would pick an owner surrendered dog when I adopt.
Potty training is not the biggest challenge, I potty trained my previous rescue in 2-3 months! Just have to be consistent. It's the yelping and other psychological problems that are harder to fix. I don't know the background of the dog you're looking to rescue, but just know it's a lot of work. My previous rescue snapped at my dogs, but she gradually got used to them so there was never fights or anything. If you choose to rescue the dog, good luck!!
