Monique - so glad everyone is doing well. I wanted to mention that we had a similar incident with a neutered male Springer Spaniel, Beau. He was about 8 years old and we brought a rescue Springer into the house - she was in heat, and we assumed since Beau was neutered, there would be no issue until we could get her spayed. Well, not only did he manage to fully engage contact with her, they got stuck! And I mean S-T-U-C-K. Cold water didn't help. Screaming, yelling, and begging didn't help. I immediately called the vet - and it was after hours at about 10PM so I had him paged. I told him what was going on and asked how it was possible. After he calmed me down he told me that this is only possible in about 10% of neutered males. He said it is some what unusual, but it does happen. And they are indeed shooting blanks.
Needless to say, we had our new girl spayed as quickly as the vet could do it!
