2–3 weeks in with at least 30 minutes play a day with a Doberman/Shepherd X (not a soft/bite) and as yet no holes. Whilst the decals wore off pretty quickly the material itself is largely unmarked. This dog usually has a hole in regular dog Frisbees in the 1st session and destruction in a couple of days. I went with the Blue and she's never had a problem seeing it day or night. If there was a flurry model it would be perfect.
