He is a beautiful dog! I commented on your other post regarding your construction project. Our anxiety filled dog benefited from working with an experienced & patient trainer and us, to build confidence and tolerance, which then helped with so many issues like noise or separation. She taught us so many tips and tricks to help her. It's really important to develop routines or situations he can tolerate before he winds up with serious issues. And walks or exercises to tire him out helps too. There is really nothing worse than an unhappy dog who doesn't know how to behave the way you want him to. Those situations seldom work out well. Spending time now would be well worth the results you could achieve with Cookie! Best of luck to you.
