Harley has been growling a lot lately, but not snapping at all. Still I'm concerned. He is sneezing a little, but he is eating his food and treats. He is a bit sluggish at times, but is his normal wild JRT a lot too. Should I call the vet or wait a few days? If it's anything it is probably just a cold. (It's 6 degrees actual temp here!) Also I am remodeling my room, aka Harley’s room, so that might be upsetting him too. Any suggestions on what I should do?
