Lol, yeah, I've never seen any "balls" popping out of there but there was ONE time where I almost threw up. lol. It was about 2 weeks after Jackson was neutered and he started goin' at it with a stuffed bear. All the testosterone was not out of his system yet, I suppose, but when he got off the bear, I was like WTF! I had never seen a small dog with such a big... well, you know. He was standing on all fours and the thing was near touching the ground, red and sticking out. Needless to say, I was pretty grossed out and my little brother was all like "What?!" and we wouldn't tell him, lol. It hasn't ever happened again and I hope it doesn't!
I know it's part of nature but I'd rather not see my dog like that.
