Has anyone ever had a bun who does not seem to chew on anything? I've been noticing that Obie does not really chew on stuff like the other buns. Its not a new behavior, he never really has chewed stuff since we got him. We have tried several things - sticks, pinecones, wood blocks, cardboard, chew treats. He loves his toys, a thick paper tube, baby keys, a string of wooden blocks and a wire ball. He tosses them around and puts them in things, but he does not chew them. His teeth do not look too long...I will be checking them again soon. He was a rescue bun from a poor previous home - is it possible his not chewing is from something in his past? He's a healthy happy bun, his vitals are good. He's a binky maniac when he's out. Just wondered. Thanks!
