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/
I once had a pup under treatment at the Bristol Veterinary hospital. When they finally sorted the problem I was told now you'll be able to give him real food meaning kibble!1
I always feed raw and whatever but never complete dog food. Having said that it seems that over here we get a new dog food manufactutrer every month and all claim that theirs is the best!!
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.
The truth is all dry dog food has been processed and heated to death as to make it a poor food item no matter how good the ingredients are. Just look at it. That dry, crunchy pellet was actually meat, veggies, etc at one time.
I went to two health food type pet stores yesterday and asked a bunch of questions about the different types of holistic dog foods and other foods that they had. I came away from both stores with several brochures and tons of food samples!! From one store I got a plastic grocery bag FULL of Timberwolf Organics and from the other store I got a bag full of EVO Innova samples. Enough to feed these guys for more than a week!! I had no idea that you could get samples from the stores!! The dogs seem to love both brands. We're taking it slow though so I can keep track of the reactions. They currently eat Nutro Max Ultra Puppy.
