This is very interesting--and enlightening--and would certainly explain our experience. Do you work at a vet's office? I'd love to have some information to pass along to my own vet since he said he had never seen this before.
Our sweet boy seems to be himself again. By last night his panting and interest in our other dog seemed to be gone--which is a huge relief. I am also wondering if the anitbiotics the vet gave my other dog kicked in. It could have been we were dealing with a double whammy: peaked testosterone levels plus an infection giving off false signals.
Thank you very much for your input. If anyone else I know ever goes through two male dogs being neutered, I will pass along this very helpful insight.
