Just got home with my puppy after picking him up from the vet where he got his ears done. His ears look good, not bleeding much and they are posted with a bit of styrofoam and he has an E-collar on. The vet told me to leave him in a dark and quiet place so he could rest. So I did but he just screamed and barked and cried and howled like he was being tortured. Finally I let him out and gave him a little food and his pain medication like the vet told me and I put him back in his crate thinking a full tummy and the medication would let him rest. He just started screaming again, nonstop. My mom got me to let him out in the living room because she thought he would be happier. I gave him a porkhide to chew on but he can't hold it with his feet because of the E-collar. So he's simultaneously struggling to chew and crying nonstop still. He's obviously not happy and it's killing me. Is there anything I can do for him?
