Le Oceaia 🐞 β€’ 3 Fur Babies 🐾 🐞🐾🐢

So I have a special needs dog she is a tripod and blind. We are going to have to get part of her leg amputated. She is almost 6 months and we been having such a hard time potty training her. We tried everything! Does anyone have any suggestions on what we can do? She pees a lot especially during the night we take the water away at a certain time. So she don't and that has helped some. But like nothing is working! I NEED HELP!!!
