Hey all! I'm new to this website. I'm posting my concern here since I'm not sure if its behavior or there's some underlying issue no one can seem to find with my dog. My fiance and I have had our german shepherd for four years. We got him when he was 2 years old and was badly abused by his old owner. He's had some health issues like allergies, constant ear infections, anxiety, and issues with his leg that his old owner hurt badly. Three days ago, his behavior changed out of nowhere and for no apparent reason and we cannot figure out what triggered it. Our GSD paces non-stop, he was panting the first day constantly. He kept us awake all night the first 24 hours. He has the need to be near us all the time. I first thought maybe an earthquake or something was coming but it kept going on and on. Now sometimes he's suddenly afraid where he bolts away if we try to call him over or try and take him outside but he will still come and hang out with us. He isn't whining or seems to be in pain. He still loves going on walks and his issues are really bad only at night. It like comes in waves but he seems nervous/anxious/antsy all day long. Last night he finally slept through the night for once. i'm growing more and more concerned. He's definitely not at the same point of pacing as he was the first night but he is still acting very strange. Our dog has NEVER had this behavior before. Yes, we know he has anxiety but it has NEVER been this bad. We've taken him to the vet and have tried to get several opinions from different vets but they just say its anxiety. I'm worried for our boy and we want to fix this asap. Has anyone run into this before? We're desperate right now.
