I switched my 7 yr old black lab to Kumpi @ 3 months ago.  He was previously on XXXXXXX for several years but as he grew older I noticed various issues developing including lower energy and gastrointestinal problems.  I then switched him to XXX high protein (their marketing and related research was very convincing) for a few horrible months resulting in even lower energy levels, itching, and terrible stomach problems.  I was just about to switch back to XXXXXXX and be resolved that he was just slowing down due to age when I became aware of Kumpi.  After much research, I purchased a bag (drove 35 miles away from my home)  I am amazed at how much his activity level has increased, improved coat, and no stomach issues.  He hasn't acted like this for 3 years.  Now I discovered that you deliver directly to my home, even better.  Thank you very much for developing this food and improving our dog's life.  
Best Regards,
Anthony
