Hi Marv's mom and Marv. Welcome to the site!
Sorry to hear about Marv's diagnosis. My bully's on a raw diet and I, personally, think it's fantastic, but I admit it's not for everyone.
If you feel more confortable feeding kibble, a lot of people here choose Fromm or NVI. They're great food with a lot of benefits. These brands are highly ranked in our dog food rating system, so that may be a good route for you to try if you'd like to stay away from raw. If you can't find either in your local shop, Petflow is an internet based store that offers delivery which a lot of our members use. Hope that helps!
