Hi I have a 18 month Pembroke Welsh Corgi that has been acting strange since I came home from school. He's acting scared to come close to me and yelped when I tried to pick him up. He goes into his crate and sits all the way in the back staring at the side of the wall. I noticed him eating some food before going into the crate, but he didn't drink any water. He doesn't respond to any type of play, toys, treats, lasers.... etc. Just looks depressed and scared. Please any insight to this would be great. Thanks
