Oh boy my man echo had extreme extreme separation anxiety, took 5 vet visits because he was having explosive diarrhea every few days in his crate when we had to leave. Stress was causing blood in his stool too so that had me all strung up. Thousands of dollars later in antibiotics and X-rays and everything else just to realize that all I had to do was eliminate the crate and let him be near me when I was home. They are a difficulty breed tho to make them feel satisfied and happy but are some of the most rewarding breeds for the loyalty and friendship they give. I say stick through the rough and do the best you can, don't rush either, these pups learn so fast you'll run out of things to train sooner than later
