It must be a few months now that Ebony hasn't been chewing as much, he is nearly or around 2 years old. The vets said to bring him back if he couldn't eat but apart from not chewing, he is fine and not to worry too much. He will chew cardboard, but it takes him a lot longer than it used to, and he doesn't chew wood anymore. He does still do all his other activities as normal and is still active, the only thing that has changed is his chewing. Not sure how he is managing to eat his food as normal, but somehow he is managing to and has been managing since he got his teeth problem. But shouldn't his teeth be better by now?
