Ok, so I knew to expect the hair color changes when I got my boys. On their first grooming visit... I went to pick them up after they were there for 5 hours... and I HAD to ask the groomer if they were mine! HAHAHAHA (ok not really!! I knew my own dogs, but thats how different they looked!!) all the black was GONE on my big boy! he is now tan & silver! It was like they cut his puppy hair out and suddenly there was his real color all hidden underneath! Hes soooooo gorgeous now! I liked the black too... he was an adorable puppy! But now he is a handsome young man!
