I tried to get to the bottom of it, but I didn't find much. I did find an article that said food prices in general may be rising due to El Niño, so that may be a factor. Also, an article about general consumer dissatisfaction with higher pet-food prices: http://www.petbusiness.com/January-2016/The-Cost-of-High-Prices/
And, stats from last year that show that pet food prices fell to a fairly low point in August 2015 (which may explain why they're going back up now): http://www.petbusinessprofessor.com/petmarket/buying-pet-products-price-matters-petflation-update-and-more/
@Ellusionz:
I've just swapped my dog to Wellness Core. It's high in protein which I was told is really good for the basenji breed with how active they are. Also grain-free. But they say it shouldn't be fed to dogs younger than a year. They sell it at Petco. There's also the regular Wellness that Petsmart carries thats been rated just below the Core. I researched the ingredients in the brands on dogfoodchat.com
I thought about going with a high protien …. i'll deff look into that for next time after this huge bag is done :)
I agree with Pat. If the 'best' dogfood gives your dog gas, or loose stools, it isn't the best for that dog.
Like Petra said, you feed a good to great quality food, hi or medium protein, whatever your dog likes that agrees with them.
We just switched to Canidae over Nutro Max. We've fed our others Nutro for years and haven't seemed to have a problem, but I'm curious how the dogs would feel if they ate a better mix. Canidae has a very good ingredient list and got a A+ rating on this list! It actually isn't noticeably more expensive per pound than the Nutro we've been getting. A 40# bag was $40. So far they gobble it up, so they must like the taste at least.
