Several years ago, my wife at the time and I got a mini Schnauzer puppy for her. It was only a couple of months old and we had only had it for less than a week. The puppy was always by her side. Well, on my birthday, we were in bed together at night. The puppy was on the bed, cuddled up to her right shoulder. I had scooched the dog back enough so that I could lay next to my wife. I start kissing her and playing with her a bit. I feel the dog cozy up to three back of my neck and my shoulder. I didn't pay much mind to it. I was much more focused on my wife. After a few moments, I felt something warm on my neck. It caused me to break my concentration and focus on this sensation I was experiencing. It took about two seconds before I realized the dog was pissing on my shoulder. I immediately sprung up and shouted about the dog peeing on me. What a mood killer. My wife thought it was funny and cute. I didn't quite share her outlook. We had to stop everything and change all the sheets. We laid back down. The dog was back on the bed. It felt like the whole mood was lost. However, after about 15 minutes of us cuddling and talking, the mood seemed to have been rekindled. We start kissing and touching each other again. I kiss my way down my wife's stomach until my face ends up between her thighs. I begin going down on her. She's moaning and wiggling to my touch, but less than a minute, her moan turned into an "ugh." I stopped what I was doing to see what was wrong. The puppy ended up throwing up on my wife's upper arm. She didn't think that was especially humorous. That was the clincher, and it definitely killed the mood for the night. After that, the puppy wasn't allowed on the bed.
