I tried royal canin for a while after the problems of supply occured with Nutro , I didnt like it myself it gave all my girls bad wind <<phew>> and the whole family sufffered, I decided to go with Arden Grange and the wind stopped but I cant remember it being extra smelly with the other food...
Fit and fertile have a supplement which also helps control the smelly poo

ALTHOUGH a good food really doesnt require you to supplement ,I gave it to my bitch after she had her puppies to keep her coat in good condition.
