Husky approved
I have a 60 lb husky and I was buying blue buffalo dog food for a long time but it’s getting to expensive..a 30 lb bag is around $60 and I wanted to try something different for a little cheaper but still good for her and so far first time trying and she loves it. Glad I bought it. This is way better deal for 30 pounds and still gives my dog healthy benefits ð¶

Happy/Healthy Poochies!
Costco dog food is cheap but, kinda like feeding your kids Top Ramen 3x per/day. Also, it smells awful.Iams however, smells like food and makes my dogs healthy and Happy!

Never had issues. (Bites are huge though)
I’ve been told how low quality Iams brand is, but my dogs never had an issue with eating it.I mean, like every other brand they get bored of it, but other than that, no intolerances.The Large Breed dog food is really big though. I feel like since for older dogs, tintolerance. make them so big.

love it…
My two 60# dogs have been eating this for several years. They get 1 C morning and 1 C evening. It maintains their weight very well and the vet is always impressed at their skin, coats and weight.

Don’t listen to the Dog Food snobs (yes, like many other consumables, there are dog food snobs nowadays) this is good stuff at a good price. Our older 7 year old dog likes the senior and since she is a larger breed she prefers the larger bite, so that’s what she gets. It’s really not that big of a chunk though. I would have thought it would be bigger, but it’s better than the normal size for a larger breed dog. It gives her that satisfying crunch, whereas the smaller stuff she just sort of swallowed it whole a lot of the time.I don’t know if it’s fresh, I can’t tell. It smells like dog food. To me all dog food smells similar, if not the same. She eats it. Her poop stinks, like it usually does. So I don’t think there’s anything wrong with it. I think part of the issue some people have with dog food is they don’t understand that you cannot just abruptly change the brand and/or type overnight. You need to do gradually wean them off their old food by mixing in more and more NEW food and less and less OLD food over a period of a couple weeks. The longer the better and easier it will be for your dob (and cats too) to adjust. The people who speak of their this giving their dog the “runs”, well, I highly suspect that’s what they neglected to do.Getting back to the Dog Food Snobs. You do not need to listen to them and buy a $100 bag of dog food. That’s just nuts. When I was a kid we had a dog that lived to 16 on some Co-op brand dog food (Co-op is a Canadian farmers co-operative store for purchasing supplies and farming related products.) Consumables, like this dog food could be purchased in bulk in massive bags, probably 40 or 50 lbs each. My dad would split a pallet with our neighbour, have it delivered and have the bags off-loaded by hand and carried into a cold storage area under our carport. A shipment would last us, to be best of my memory, about a year and a half.The quality of the dog food itself was not high. It was dirt cheap. Really cheap. Cheaper than even Purina Dog Chow which was the only other dog food brand I can recall from that time period. I know there were a few others, however. But this Co-op stuff, which came in a plain brown bag with very little written on it as far as brand recognition is concerned, would probably make today’s coddled pure breeds vomit just by swallowing a single nugget. But our dog ate it…and loved it. And her bowel movements were so regular you could set your watch to it.Anyways, she was as healthy as a horse to the day she just went to sleep one night and did not wake up in the morning. No major issues whatsoever during her lifetime and she was a Heinz 57 breed (she looked mostly like a lab but she obviously had a few other breeds in there somewhere.). And our cat lived until at least 22 years old and lived off that old IGA store brand canned cat food that came in only 1 flavour – FISH. That is all he ate his entire life (with the exception of mice and birds and whatever else he managed to catch outside).Now maybe that Cat and that Dog were the exception to the rule, I don’t know. But we had other dogs and cats with similar life experiences with no serious health issues.Over the course of MY life, the only serious health issue my pets have had is when I’ve had a PURE BREED. One when I took in two pure breed Saint Bernard adults from a client who could not care for them any longer and another when my wife brought in a German Shepherd adult into our marriage (purchased by her ex-husband who then proceeded to totally ignore the dog and let his wife train and raise the dog completely on her own).And the most recent was when we adopted a Newfoundland puppy from our local Humane Society. My wife and I both thought we best adopt him as we knew what we were getting into and were prepared for a GIANT dog.All were great dogs that I loved to death, but they all the Pure Breeds had health issues that were well known issues within their breed. So going out and spending a couple grand on a pure breed just because you want a conversation piece and to show off your social status is simply contributing to their health issues in the first place.Well, sorry for the rant. I’m just saddened by the amount of people I see who go out and pay big bucks for a pure breed status symbol dog, cage them all day long, barely spend time with them, and the dog is lucky if they live for 10 years, all the while dealing with well documented health issues brought on by the generations upon generations of in-breeding.Getting back to the task at hand. This food has quality ingredients. But if you love your dog and show him/her that love, they will be just fine. Get them the proper and recommend vaccinations. Just be aware of veterinarians who over-vaccinate. By no means am I an anti-vaxxer, but please be aware that for quite a long period of time a great deal of vets were over-vaccinating pets, contrary to what the vaccination makers guidelines recommend. Ask your vet and stress to them that you do not want to over-vaccinate your pets. Most vaccines are good for 3 years nowadays, but I am aware there are still some vets out there, in Canada at least, that insist they still need to be given annually.

I have an elderly lab whom has gotten so fussy in his old age and have tried every dog food you can think of.i have tried Iams before but not this senior formula.so once again I bought hoping he would eat it.well he eats and eats it all up.the bag is huge and the price is reasonable considering the brand.
