I have an issue I can't seem to find a link to. Yesterday morning Sarge's muzzle swelled badly on the upper left (whole side of the muzzle). We were outside at a festival all day and I initially thought he bit a bee and got stung. Slept way more than usual all day but is still eating fine and taking water. I looked this morning and can see a tooth breaking through. Anyone's pup ever swell up like that when cutting teeth. Swelling seems to be down a little this morning but still very tender and touchy. Any ideas? Worth a vet visit or wait a day? Thanks
