Hi I wondered if anyone had experienced the same as me or could give some advice?

I have a 7 month old puppy that has been brought up on royal canin since birth. She is a black and white bitch and originally her knickers were staining yellow, that normal sometimes. As time has gone on it has got worse she now has staining down her neck in her arm pits and the insides of her legs.

She was on royal canin mini with a couple of cubes of natures diet raw meat mixed in. I saw royal canin rep who has put her on royal canin golden retriever puppy.

She doesn't have yumega as that does tend to stain lighter colour coats.

Someone suggested it could be the protein levels has anyone come across this before or she'd any light on the matter I would be really greatful.

my girl is on in and was raised on it and ive had no problem but the guy who runs the pet shop where i get my mouse food from said he raises his pups (boston terriers i think) on it but swiches them off of it after a few months as they get staining and lose fur on there heads because of the protine lever in it. My friend with lhasas wont feed it as her dogs beards got realy stained with it apperantly.

I stopped feeding Royal Canin as it sent mine (all 5 of them) into itchy overdrive.
