Tried a few dog foods for my Rottie, but she had really BAD GAS and regularly vomited. By chance the pet store was sold out of our usual brand and we were given Pro Plan Salmon and rice to tie us over until our food came in. I had none of our usual food to mix in with it to gradually switch her over, so I was nervous. But to our surprise she had no bad reactions to the quick switch. In fact we were amazed to find that there was many Benifits to the salmon flavour. She is no longer a GASSY girl. No joke!! Also she is rarely vomiting! Her coat is soft and shinny and never has dry or flakey skin. Love the goodness and enjoying the fresh air! Lol!
