my dog is behaving strangely. he is looking up up in the air like something is there, sniffing extensively, and kind of acting like he's on a drug or something .we are very worried about him.any ideas of what could be causing him to behave like this

Call them. If they want to see him they will tell you. Remember too that dogs have tremendous scent ability and with the warmer weather there is alot of smells about.

The office will open in the morning, and im sure you could run that by them, im not a vet but i dont think there's anything wrong with the looking in the air or sniffing , my dog does that frequently. I dont know about acting like hes on a drug, hopefully he didnt get into something
