Hi, I have this beautiful 5 month old girl from the shelter. I got her when she was 3 months old and she has grown big since. They told me she's a mastiff cross. They weren't sure what she is crossed with. She's starting to show some behavioural problems with my 4 yr old son. So I'm trying to find out more about her breed details. I asked the shelter if she will be a large dog as I know mastiff is a large breed but they assured me its only going to be a medium size dog because of her paws.
Can anyone tell by looking at the pic what she is crossed with?
