As many of you know, when we moved in here the previous tenants left some two week old pups. We kept three of them. They are great about barking when some one or something is near and never had a problem at all until today. Ken was mucking the coops and one bird decided to rest outside while he did his thing. No sooner did she walk outside when one of the pups pounced on her, grabbed her by her neck and started shaking her. DSS caught the dog within seconds so the bird was unhurt, but I can't have those dogs NOT protecting the birds!!!! They are 5 months old now - any suggestions??
