While I was on a conference call today, my wife brought our dog in and had me feel his underside where he was neutered. She was panicked because it was hard down there, like some type of abnormal mass. She quickly called the vet and they told her that when some boy dogs get excited, their glands swell up and it gets hard. Sure enough, a few minutes later things were back to normal. I’m so glad that we didn’t have to take the dog to the vet; I love my dog and will do whatever we have to for him, vets scare me. We spent way too much time at the vet with our last dog.
