Babies can be nervous and nippy on the get go so it could be hard to tell if it was stressed or just being young. I haven't had any problems with my rack being in a room with my other snakes, and tarantulas. The cat and two dogs go in an out with no signs of stress. Its also my art room with my drafting board and looms. With my constant cleaning and being in and out I haven't had problems. They have hides in their rack so thats a little extra security. I have had nervous Bps and rock steady ones. Its really gonna depend on the individual.

I think the main concern is can the dogs get to the snake? Can they knock the rack over? Scratch at it and so on..

Luck to you!
