Hi, I have two border collies and a border collie/jack russell cross.

One of the collies and the cross were fed Hill's Science Plan for ages and then we moved them to Purina Beta after trying a few other things. Bakers Choice and Pedigree both had 'interesting' results and I wouldn't go there again.

The youngest collie was fed Eukanuba puppy as soon as he got off mum's milk and tehn onto Beta for him too.

After speaking to our new neighbour (we've just moved) we've tried them on Chudley's. The crazy thing is that they all prefer it and are in even better condition, even though it's very significantly cheaper (about £12/15kilos). The male adult border collie gets about 230g twice a day, he's around 20 kilos. The food is a mix of kibbles and muesli-type stuff. http://www.chudleys.com/products/dog...-dog/original/

Having tried the expensive stuff, yes it works, but it seems that something else about a third-quarter the price is just as good... It's sold as a food for working dogs, and round here we have to go to a little shop a few villages away to get it, big pet shops seem not to want to stock this range...

Possibly a bonus or possibly coincidence; but Merlin the big lad is a Blue Merle and has always had problems with some of his pads - some of them are pink, and playing on hard surfaces too hard has always been a reliable way of giving him a bloody foot. This has cleared up since going onto the Chudley's original. I'd recommend anyone with Collies to give it a go...

Edit: should make it clear that i haven't been trying to make his paws bleed, we've just never had a gravel drive before...
