Hi. I am learning how to animate animals. But when i am in a pose mode trying to animate my rigged wolf, his mesh stretches which is very annoying because i do not want my wolf to be looked like a puppet ( can i find somewhere preferences for the mesh stretch and set it to zero?) and also i do not want his legs to be fallen below the ground level, so is it any constraints or obstacles i can set for the ground, so the ground will be kind of impenetrable surface for the legs?
Thank you!
