Something is going on with my 8 year old golden retriever. He woke us up early this morning, pacing and panting. I got up with him, took him outside where he wondered around eating grass for half an hour. He's really agitated and panting and won't lay down. He wants to be outside eating grass. He ate his breakfast and is still drinking, and has NOT thrown up, but I'm concerned. The panting and agitation worries me.
Any suggestions? Anything I can maybe give him that might help?
