My name is 2 females!

These 2 female Great Pyrnees were dumped in my neighborhood. They are currently residing in the Mcloud animal shelter in Oklahoma and are due to be put down on 11-19-25. I am looking for someone or someones to adopt them. I can't take them myself as I have 4 dogs already but I can pick them up and drive them to where ever they need to go. The city of mcloud facebook page says they found their home but they were returned. I'm told the adopters returned them because they were agressive with the dog they already had. I don't know if this is because they are stressed or acting as pack instinct. maybe if they are relaxed or adopted out separately this would be different or adopted together into a home without other animals. I'm just looking to keep them alive. It's not their fault they were dumped.
