Friends I need help! Coopermy dog started exhibiting odd behavior at my friend house after trying to play with her cat. He acts scared, and anxious. He's also off balanced and shaky. He doesn't want to eat or drink and I'm freaking out. He seems fine for a second then he will jump and kinds freak out then drop to floor scared. What do I do. Is there a vet that makes house calls at this time on a Sunday. Please let me know.
