I have older dogs two of which gain weight easily. Does senior food have less calories? They currently eat the regular of this brand and I have to keep cutting back.
Answer by ChewyNov 07, 2017
This Food contains 318 kilocalories per cup. The Diamond Naturals Large Breed Adult Chicken & Rice Formula Dry Dog Food contains 327 kilocalories per cup.

I am interested in this food for my senior pup. How many cups can I get per pound?
Answer by ChewyJun 25, 2018
There's approximately 24 cups of food in the 6 pound bag, 72 cups of food in the 18 pound bag, and 140 cups of food in the 35 pound bag.

What age do you consider senior for this food?
Answer by ChewyNov 05, 2017
Senior formulas should be given to pet's that are at least 7 years old.

Is the guaranteed analysis measeured by kg? Then a serving size is mesured in cups. If I save my senior dog one cup a day how much glucosamine and chondroitin would he be consuming a day?
Answer by ChewyApr 01, 2018
The guaranteed analysis of the food goes mostly by milligrams and one cup serving. If one cup is served then your dog would get 720 mg/kg min of Glucosamine and 240 mg/kg min of Chondroitin.

It's okay

My 1 dog,Scotty,will eat anything but my other,Grim, is very, very fussy and is not impressed with this substitute for her usual Victor(same company I think) but she doesn't seem to like the Cherio shape. She will eat it with some canned food mixed in. Unless your dog is fussy the food seems good although even when mixes with the leftover not recalled Victor they both had looser stool for a week. Not a bad food but after about 8-9 years we're looking forward to going back to their normal diet.

Good product. Great service. Please improve shipping.

This 35 lb bag was bundled in a big box including a small box of Vita Bone biscuits, the latter's integrity supposedly cushioned by some flimsy paper. Wrong. The Vita Bone box was shattered as were a number the biscuits. I recommend both products; however, not Chewy's method of packing without thought of how adequate cushion would protect contents.

Looks like my bag was cut open

I brought this bag in and my dog was more curious about it than usual. I open the box and find loose food everywhere (makes sense why she wanted in the box) The bag looks like a knife has been taken to it.
