Hi, she chases cats if she gets the chance, but not sure about chickens and goats. When out walking she is always the first to go and say hello to other dogs, but not really been around them as such other than in passing on the street. Most of the time she is OK, but can snap if a dog rushes over to her first . Yes she can be off the lead as my husband has her off the lead quite a lot, I normally like to keep her on but that is just me. Would you be interested as it sounds like you have your hands full already? Do all your dogs live inside? Have you a garden? I can phone you for a further chat tomorrow if you let me know your number if this hasn't put you off. Thanks. Caz
