I have a 5 1/2 year old male - intact- Springer...(he became a Dad last Fall )

I have alwaysfed him Artemis dog food and would not consider changing to any other brand unless
instructed by his Vet.

It may not be the most popular brand but it certainly warrants looking in it.
I highly recommend it.
