OG - I'm not under the assumption you are a bullshitter in any way, shape or form. You are trying to validate something with TopShelf's argument. To argue TopShelf, I can offer my own experience. I was a collegiate football player and a national level Powerlifter with top lifts of 804 squat, 568 bench and a 722lb deadlift. During college, you can bet, there were times sex was enjoyed literally MINUTES b/f some practices and the night b/f games. The same can be true of my training and competitive lifting. I experienced nothing TopShelf experienced himself. SO, who's right? We have experience vs experience in referencing sex and it's affect on the "rear end of a male".
This argument reminds me of Jack's with the DE. There is no science to back up any of this. TopShelf's references to 7 days prior is actually assinine. Hell guys, I can have blood drawn, which will, no doubt, weaken the athlete, and STILL compete at full strength within 6-10 hours.
The bottom line with your dog, I believe is you had yourself a dog with "problems". The fact he's jackin off every day proves it. An unsound dog, in any area, is a dog that is more susceptable to losing than a sound dog.
You believe what you want, but breeding a dog the day b/f anything will not affect the 'anything' in any way. The actual action of sex and the loss of semen does not do that. Now this could coincide with other factors leading to a performance loss, but the actual sex and semen loss, the day b/f will not lessen a dog's strength.
