I used to hunt years ago with a GSP. I've just come back to bird hunting and now own a Boykin Spaniel. The dog, despite my training efforts is doing quite well. My question is on Grooming. Does anyone have good tips to keep burs out of the coat, especially around the ears, a short afternoon in the field, and my wife and I are picking burs out of his coat the rest of the night. Is clipping the coat short the only real option?
