Two Horses and a Dog

Two race horses were sitting at a bar having a few beers when one turns the other and says,
"Jerry, something really strange happened to me at the track the other day"
"What happened Bill?"
"Well, I was running a race and I was stuck in the middle of the pack trying to break away. I thought I would lose that race but then I saw a strange light flash from the stands. I turned and looked at it and suddenly 'WOOSH' all of a sudden I was at the front of the pack and I ended up winning the race"
"Holy Shit", said Jerry.
"Bill, thats exactly what happened to me only a few days ago. I was running a race and about half way, I started to drop back. I thought I was going to lose for sure but then I saw that strange light coming from the stands. You're right Jerry, it just seemed to get brighter and then suddenly 'WOOSH' there I was five lengths infront and I ended up winning the race."
As the two race horses discussed the incident, a Race Dog sitting at a nearby stool came up to them.
"Excuse me lads," said the Race Dog. "I couldn't help but over hear your conversation and I wanted to let you know that that very same thing happened to me about a week ago down at the track. I was running a race and struggling on the outside lane trying to get some space when I started to drift further back and away from the lead. I knew I was going to lose that race but then that very strange light that you boys had just described started pulsing from the stands. Well, as you may have already guessed, 'Woosh,' there I was up at the front and I ended up winning that race although I've never been able to figure out exactly how."
The two horse were awestruck.
"Holy Shit, Bill, did you just hear what I heard!"
"I know," said Jerry. "Its a fucking talking dog!"
