Now I dont what to make of this. Winners have lost weight, gained weight, stayed the same. Fluctuation I call it. These weights are given when they weigh them at the track at whatever time. The dogs then walk down to the boxes release some tension, and have a bog or a piddle somewhere. Some dogs do, some dogs dont. And I dont know what to make of that.
On the grv formguide it has winning weights.

Race 6#1 Hotline hero won. This weight.36.0
his winning weights:
35.2 kg (2) 35.6 kg (2) 35.8 kg (8) 36.0 kg (7) 36.2 kg (2) 36.4 kg (3) 36.6 kg (3) 37.0 kg (2)

Race 7 #1 This weight:33.4

Race 8#7 this weight 31.2

Now since you have read the winners weights, lets see if anything reasonable pops up in the losing dogs. TO see whether there is a *reason.

Race 6:#2 This weight 39.2
Winning weights:
