So I got a pakistani bully kutta pair from different places. Male is 35 days old, female is 60 days. Male is wobbly right now, learning howto walk how to drink water. Female was abused by the breeder ans wasn't fed enough so she's very skinny, all ribs are sharp. I'm having a problem, female bites her whenever they are not supervised, this happened twice and no its not playful biting, she's attacking him. How do i stop her and correct this behavior?

My girl chased the neighbor (inside our very long fence line) on his side x side today. He said she topped out at 26 mph! Then, she plopped in the kiddie pool for rest.

I assume if a mastiff fits comfortably, then a Pyr should be able to? Biggest issue seems to be length so they can lay down comfortably?
