If you have the trouble I had with the bigger dogs, which is that the bottom teeth seem to change the geometry in such a way that the saw can't torque the chain when those bottom dogs get dug in, cutting them off worked. Cut them off with an angle grinder, actually my brother in law did it for me. And, no adverse performance on everything else about the dogs, glad I changed them and glad I have them. The 460 is an excellent saw.
