Hi, I wasn't sure whether to put this in health or behavior but as its the way his acting that is bothering me I'll start here. I have a 5 month old border collie. He had surgery on Tuesday to remove cataracts from both eyes. We brought him home Wednesday and he was himself if maybe a tad subdued, Thursday he normal. But yesterday and today he is acting completely loopy. My boyfriend thinks he is just happy to see clearly for the first time, and I thought he might seeing things as he has a lot if drops and I don't know how those affect his vision. He is on the go from the moment he wakes up and seems constantly on edge, sometimes he is wagging his tail and other times he looks like he is on alert. I currently have him shut in the living room with me and he is running around attacking randoms bits of carpet and nipping at the air but there is nothing there. If I let him out in the garden he will sprint and jump around chasing nothing, he has even started ignoring sirens which used to bother him before. I might as well not exist I can't get his attention even with treats. On the other hand I was wondering if this is partly due to him becoming an adolescent collie that needs more exercise and training. I just really need him to calm down he is like this all day. I will try taking him to the vet later to see if they have any insight.
