During that puppy to adult coat phase I've had good luck with Pet Head's Furball Detangling Spray and a simple comb. Spreading out that weblike knot makes it fairly simple to get out.
I rarely have those anymore since I started doing his final comb using a flea comb. Those teeth are so close together that it catches any snarls way before they have a chance to turn into anything. Also very handy for combing his nose as the small size is perfect for facial grooming |
