Need to rehome

This is Violet.   She just turned 1 year old.  She is updated on her shots, and is spayed and microchiped.   Violet is very energetic and playful.  She likes to run and hide under the bed and  then pop out playfully.  She is NOT good with cats!  She is good with my 9 year old son but has not been around other kids. She also gets along with my older female dog but I think she would be best as an only pet or just one other dog because she does not get along with her sibling at all which is the only reason I am rehoming her.
