mooee, a drop in weight may be that the dog has a little more stamina (not much), but the downside is, and this is generally speaking, that it's not as 'alert' or as quick early on.

All you need is a copy of formguides which show the positioning of the dog in the run, and check how it performed with any previous weight variations.

Find a dog that has early speed and plenty of ticker ..... and can run a decent time ..... and has won a decent race ..... and IF you MUST bet from the couch, this may be the best way to go. In my opinion you've got next to no hope assessing the form using form guides from home.
