Dog Food Question. lol

[3Roosters]

I know I know.. I opened a can of worms. lol. I am not asking brand or if a dog's tail is docked. hahha. But my question to the peanut gallery is if any of you have switched up..either the brand of dog food..or the main ingredients or both as your dog as aged?
I am thinking of switching up for our 10 yr old Springer.
She hasn't been quite as voracious at feeding time for the last month...not really being picky mind you..but not as interested in chowing down. All other signs appear fine...weight..no vomiting, diarrhea, etc. sleeps seems normal as she ages.
This is our 3rd dog and just wondering from the peanut gallery if changing things up...gradually of course..may be a good thing..Perhaps she is bored??? OF course I do not want to develop a damn picky dog..just wondering..perhaps we should change it up.
Without divulging the brand. She has been on salmon and sweet potato for years. Think its 25% Protein 15% fat 4% Fiber. I hunt less than before..if that plays a part.
Thanks in advance...

Mixing up might peak her interest a little bit. I am Taste of the Wild Sierra Mountain for my dogs, past and present.

Have a 12 yo Wirehair that had both ACL's repaired when he was 5 yo. He stays in shape year around. Noticed about a year ago that he was showing down when walking / hunting. We changed feeding regimen going to Fresh Pets and supplementing with a lot of veggies, pumpkin, etc. We have seen a dramatic change in his coat, muscle structure, and overall level of energy. A little extra effort but not realty any more expensive than the science diet we had been using.

We have fed our dogs Blue Buffalo Wilderness for years, never change, never vary - they freaking love it! The wife dehydrates sweet potatoes for snacks - love them. Also get them Blue Buffalo biscuit treats. That's about it for our kids, aside from bites of apple, banana, or asparagus.
