Help please! Our 1 year old Pyr mix (supposedly she's 1/2 Pyr, 1/2 Anatolian) has been getting increasingly aggressive with our goats. We put her in with the goats at 10 weeks old, and for a long time she did great with them. She started to chase them as she got older, which would stress the goats out, so we always told her "NO" and she would stop. Lately however, we've been noticing bite marks on our goats legs, and several weeks ago we found one of our goats dead. We can't say for sure what killed her, but there were fresh bite marks on her legs. Not deep enough wounds to kill, but maybe the stress of it just did her in. When we've caught her chasing or nipping at the goats back legs when she was younger we assumed she was just playing, but my husband would immediately put her on the ground in a hold, which has worked for other issues in the past like nipping us too hard while playing. However her aggression is getting markedly worse, and my husband has caught her in the act twice this week of gnawing on one of their legs like a chicken bone while the goat is screaming bloody murder. This last attack she would not stop even with my husband running out there and yelling NO at her. Who knows how many more attacks we've missed. Our goat is now hyperventilating and not putting weight on her leg. Our other goat won't come into the barn at night because the dog is in there, preferring instead to now sleep outside in the elements and with prowling predators instead. The dog knows basic commands (sit, stay, come) and has always recognized us as alphas, but we don't know what to do from here and cannot let our goats continue to suffer like this. This has been extremely stressful for my husband, we're open to any suggestions you have. Thank you
