This morning I opened the door to let our nearly 6 month old lab/spaniel cross out in the garden. After about 5 minutes I heard him yelping and he came running in with a little stick. He dropped the stick and kept yelping. I hugged him until he was quiet and can’t work out what happened. My options are he got a splinter in his mouth or was stung by a bee in the mouth. He hasn’t eaten or drunk since and is dribbling a LOT which is very unusual for him. There is no swelling in the mouth or any where else. I’ve tried to look in his mouth but he helps when I open it. He has not peed either in over6 hours. I’ve taken him out for a little play and threw a ball, he ran after it and then yelped when he opened his mouth to grab it. So it seems a mouth or tounge issue. He’s having a cuddle now but not sure what to apart from taking him to the vet tomorrow. Any ideas?
