Odd behavior tonight

[brezofleur]

OP, yes, please get a 2nd opinion. Anything "not normal" that lasts more than a couple of hours really needs to be checked out.

On a side note, Zeus was also freaking out a lot last night! How weird. Must have been something flying over the country ha ha

I agree with those who have suggested to have liver function tested here are some clinical signs from Univercity of Tenn website

What are the clinical signs of a liver shunt?
Clinical signs are often seen at a young age and include small stature, poor muscle development, behavioral abnormalities (circling, disorientation, unresponsiveness, staring into space, head pressing), seizures, and quiet demeanor. Other less common signs include drinking or urinating too much, apparent blindness, diarrhea, and vomiting. In some animals the signs are associated with eating protein. Other animals are diagnosied when they take a long time recovering from anesthestics (i.e. barbiturates) or sedatives (i.e. acepromazine). Some animals show no signs until they are older, when they develop bladder and kidney infections and stones.

While I would never say the dogs don't sense things we can't see or hear....

Please go get a blood work up done on your pup. That definitely sounds like a medical issue..especially that he growled at you...sounds like pain or something to me.
