Over the last few days, Rockstar is taking his time to eat, sometimes taking over 30 minutes with multiple trips to his bowl. I haven't changed anything, not even his portion (well maybe I've lessened it a bit because my mom sometimes feeds him extra treats when I'm not around) size in any noticible way. I have also noticed that when I do give him treats, he takes a lot longer to chew them up, sometimes several minutes.
He isn't acting weird at all, other than not being a food super-vaccume. I looked in his mouth, and I think Its possible he may have larger teeth than before - when do corgi's generally get the adult molars? I know that sounds dumb, but I haven't looked in his mouth every day to see exactly what's going on in there. He still spends a ton of time chewing on all of his toys, never refuses treats, and isn't shy about gnawing his rawhide bones.
I just think its weird that his breakfast/dinner habits are changing. He's about 4.5 months old. I mean two weeks ago, he was checking his bowl every 20 minutes to see if more food had appeared magically.
