I'm not surprised, their coats are a nightmare. My ex had an old english when we met, he was really elderly and quite ill and I made excuses for the matted condition of him based on this, when he died ex wanted another so we got a oes pup. We kept her in full coat with the intention of showing her, I was showing zois at the time, but by 7 months her coat was unmanageable even with nightly grooming sessions. At the time I had 5 borzois, which was enough grooming for me. We had her clipped off but she always had mats even though she went to be clipped right down to the wood every 4/6 weeks. She loved the water and her coat just felted when she was wet. Not ideal dogs for most homes.
Other than the coat she was a great dog, easily trained, good natured and lots of fun, always up for racing with the hounds... but that coat can't be discounted.
