Thanks all for your input. We are lucky enough to have a pet supply right here in town, and their food prices don't seem to be much higher than Petco. I took Canuckinchile's advice and checked out the Fromm's brand. I liked what I saw as far as ingredients. It is considered a holistic food so we are trying it out. She didn't seem crazy about it last night and this morning and just sort of nibbled. But I guess she was hungry because she just finished eating the rest right now.
On a sadder note, today marks the 1 year anniversary of my beloved Sandy's passing. She was a Sheltie/ Chow Chow mix and I used to joke that she was the daughter I never had. ( I have sons.) I was so devastated by her passing that 6 weeks later we adopted Cheyenne. She's been on my mind a lot since the anniversary date was drawing near, so today we put up and trimmed the tree while playing holiday music just to take my mind off of things. Cheyenne had no idea what was going on and was barking at the trains under the tree as they whizzed around the track.
Here's a photo taken about 2 years ago of my beloved Sandy.
