This is a sharing from reader, Karen:
My dog was debarked by his breeder owner at 5 months. At 9 months, the surgeon had problems intubating him for his neutering procedure because of scar tissue. He was sent back to the original surgeon to fix the debarking. The breeder gave up on him and I went and got him. At 3 years old, he was wheezing and had exercise intolerance. I took him to a surgeon who did an endoscopy and at that time found that His airways were 45% blocked with scar tissue. The surgery to correct this was not minor. The surgeon removed the scar tissue, grafted skin over the incisions and stitched it back so that the tissue would not web in his airways again. His quality of life is much better now, he has more energy and he has a slight sound when he barks. This procedure cost $3,000 to help the poor guy. I would never, never recommend debarking as my dog suffered at the hands of the first owner and surgeon who did it to him at 5 months old. He had to be sedated for six weeks after his final surgery to correct all this. Hope this helps someone make the right decision.
