My name is Ace bonded with Ash!

Re-homing Ace and ash together. They are bonded at five years old from the same litter.
Ace gets anxious at times. He is not friendly with strangers in the home. He does not do well with kids. He did bite our daughter when she accidentally fell on him. He did not break skin but because of this I feel like he needs to be in an adults only home. He’s very obedient and intelligent. Ash is very loyal and protective and stands at my side outside of the house. He’s also very sweet and intelligent and loved to play catch and with soccer balls. Experience with German Shepards a must.
