Both those options look good to me. I checked the sites you gave and the Royal Canin's ingredients look good - no meat by-products or anything sketchy like that. Eagle pack looks good too - I prefer going for the holistic/natural varieties of whatever brand I choose and the Eagle Pack site has a holistic variety with ingredients that sound great. Not sure if that's available by you. Hopefully your dog will like one of them. By using brands that include human grade meat it should taste better and be more tempting!

I try to reward Sadie with a spoonful of cottage cheese or an egg yolk a few times a week only after she finishes a bowl of food. I hope she'll associate eating well with be rewarded to encourage her to eat. She can resist temptation to any treat, doesn't care about food at all, but cottage cheese she goes crazy for!
