Hi all We have 16 day old chicks and a 3 year old golden retriever and her 2 year old son (cross between golden retriever and probably mostly black lab). We've been cautious about allowing the dogs near the chicks, but since it's a gorgeous day, we took the chicks outside. First, the big black dog (Bear) sniffed them, we stuck close, told him, "No!" when he seemed too interested and he left them alone. Mama dog (Cassie) came over after a while and laid down. The chicks were all around both of them. The dogs (who normally get along great) started growling at each other and ended up breaking into a loud, scary dog fight! I was shocked, I've never seen them go after each other like this. Unfortunately, my 10 yo DS tried to jump into the mix and ended up getting scraped up and cut/bit in the process. Neither dog seems hurt and they're both subdued after that. What's your impression of what happened? I think Bear was being protective of the chicks or jealous, trying to keep Cassie away but I'm not sure.
