you cannot blame the dog for that...but if the dog has prey drive he can and will expose this...one of the things I find mystifying I must say is that so so many people, indeed people I consider who should know awhole lot better...NEVER REALLY OBSERVE THEIR DOGS WHEN THEY ARE IN THE ROUGH...watch your dog and you will learn more about him and how he/his breed work...its stuff not found in books or on Utube.
