Hello, I recently changed my dog's food from Royal Canine to Pedigree. He seems to not like it at all. He eats anything but pedigree. He has never been a fussy eater. He loves all kind of foods from veg to chicken. But he hates pedigree it seems. We thought may be his appetite has dropped but he eats anything else when served quickly. He does eat pedigree but only after he is way too hungry, not immediately when served. Please let me know what should I do. Is he suffering from gastric issues due to pedigree.
