Since weening our boy off Purim’s puppy food and transitioning to Iams large breed we have noticed numerous alarming and worrisome changes and after 2 vet visits and now seeing these reviews, we are swapping his dog food!!! We originally thought he wasn’t feeling well or was sad and not himself because 2 family members were traveling and he was “missing” them. (Myself and my daughter) Upon our return, however he seemed to still not feel well.
I took him to the vet for vomiting and not eating. Negative tests and the vet thought maybe he ate something he shouldn’t have. However, this dog is well trained, crated when no one is home (which is only Sunday AM for about 2-3 hours otherwise someone is always home) he knows very well he’s not allowed to eat anything unless it’s given to him. He is super good about it and listens extremely well. We also have a camera for when he is home alone and we watch him when he’s in his crate. We talk to him through it and all so he knows how loved he is.
Anyway, since starting Iams, his whole personality has changed, he’s gassy, SUPER gassy and it smell horrendous. LIKE ROTTING SKUNK or worse. It’s absolutely horrible!!! Now, I know boxers are gassy and have smelly gas, but THIS IS DIFFERENT. It’s not at all his normal. His stools are not solid anymore and also smell terrible. Again, not his normal BMs. I have also noticed he has what looks like blood as well when he has a BM. To add, my boy has been licking his paws relentlessly which is 100% out of character for him.
On google I had researched which foods were best for boxers prior to swapping him from his puppy chow to adult food & Iams was highly recommended, which was why we made the change to this particular brand. We just had to rush him to the vet again, a HUGE vet expense due to him limping and having muscle weekends specifically in hind right leg. He had a fever and was panting and having difficulty breathing. This is a 2 year old pup that loves going on walks/hikes (although hikes have been on pause for over a year because I broke my tibia), but he, previous to starting the Iams diet, walks for 2-3 miles daily and within weeks of starting this Iams dog food he rarely ever wants to move and I know something’s not right.
It wasn’t until I researched the gas issue that I’m seeing all the other issues and am quickly realizing that ALL OF HIS SYMPTOMS are as most of you describe. I am TERRIFIED! This boy is my baby. He’s my support dog and I can’t live without him. His food will be swapped. I’ll give a raw diet and slowly integrate a new kibble. The vet put him on anti inflammatory meds, but I’m calling them tomorrow for guidance! Iams you have to listen, something is wrong with your kibble. Money can’t be the bottom line. These babies are our babies and most fur parents I know truly love their pet. I am one of those loving fur moms and I need you to listen. There is something wrong with your formula. Please take it off the shelf. My boy has never had any health issues and is just barely 2 years old Please listen! FIGURE OUT WHAT'S WRONG AND FIX IT! Please!!!!
I have fed my Dobermans Iams healthy weight dry dog food for 2 1/2 years. One of my Dobermans started puking randomly. He also was reluctantly eating the kibble for about a month. I also mixed 1/2 can of royal canin digestive care. About 3 weeks ago his brother suddenly got extreme diarrhea at 1:00 in the morning. Took him to the vet and they found absolutely nothing wrong with him. Three days later they both had severe diarrhea. Even though they were on diarrhea meds from the vet.
I pulled the Iams and only fed them the royal canin digestive care canned. Diarrhea stopped in both dogs after 2 feedings Of canned only. I fed them canned only for 5 days. No puking, no diarrhea. Started to introduce iams back in slowly. Only a 1/2 cup iams dry with royal canin canned. 3 hours later diarrhea in both. Took them back off. Tried again 2 days later with 1/4 cup of iams in morning. Both had diarrhea by the end of the day with severe gas. Needless to say I am switching to another brand of dry dog food. I don’t know if it was just the 2 bags I had bought or what but I can’t take anymore chances with iams.

My dogs love Iams. We feed them dry kibble mixed with canned. I was feeding Blue Buffalo and it was horrible. My GSD had a horrible smell and a greasy coat. We switched to Iams and it's all went away. Most recent vet visit, her exact comment was "They're perfect, what are you feeding them".
Bought a green bag of small chunk chicken kibble for my pack, who usually have good appetites, and immediately started having problems. They became listless, vomited, and ate reluctantly. So I started researching and discovered discussions going all the way back to 2011 from many, many dog owners who talked about their canines getting very sick and dying. Apparently the food has a type of mold that produces a toxin similar to rat poison that destroys the liver and kidneys, and rancid fats that trigger pancreatitis and severe GI distress. Since this has been going on for at least a decade, it's pretty obvious Iams doesn't give a damn. I switched to another brand immediately and it's back to happy dogs, so hopefully whatever damage was caused will heal.
I didn’t know that Iams has been causing all sorts of health issues until it happened to my dog 2 days ago. I got a few bags of Iams dog food from a friend whose pup passed away. My 4-year-old Lab mix started throwing up on 4/6/22 and has been throwing up since. Not to mention she has had bloody diarrhea. I had to take her to the vet ER and they couldn’t find anything wrong other than irritation in her colon. They did X-rays and blood work.
After almost $1000 vet bill we determined it was her food, which was the green bag of Iams. She is on the chicken and rice diet right now. She hasn’t been throwing up as often and her stool is becoming more solid. How is Iams still able to sell their dog food after it has caused so many pets to have bloody diarrhea, vomiting, neurological problems and even as far as seizures? This isn’t okay or fair to those who have been put through so much just because they thought they were feeding their dog a good quality dog food.
I raised Toy Poodles, for 18- 20 years, on Iams dry puppy food, and I still feed it to my Border Collie and tiny Pomeranian!!! I have NEVER had ANY PUPS, WITH HEALTH PROBLEMS. THEY HAVE THICK, RICH SHINY COATS, and the only Vet bills I have ever had, were shots, & worming!!!
I switched my dogs from Beneful dog food to Iams. As of now we have been doing good on it. They seem to enjoy it. So we will be sticking with this dog food for a while. We also used Redford dog food. It was great. Only problem was that they only sold it at one pet store. That was very inconvenient.
I like Iams Proactive Health Pate with chicken and whole grain rice because our picky dog likes it. He generally will eat a whole can at a time. That is all I have to say now. Have a Merry Christmas and Happy New Year.
Bought the mini chunks for my small dog. Mixed it in slowly with her old food, and within a week she had diarrhea, going out in the yard every hour and a half to two hours to have a loose runny bowel movement, and has vomited once, yellow bile. I will now be feeding her chicken and rice if she will eat. Hope this doesn't cause a vet visit, and more important, hope there isn't anything wrong with her now. I will never purchase this food again.
Like many other people here my dog experienced the same out of control diarrhea and lethargy. This product was recommended by the local vet, as they said that blue buffalo, which I had been feeding him was not very good. Well I tell you one thing he never had projectile diarrhea from blue buffalo. This crap is going in the trash, and I’m ** pissed that this is even marketed for dogs.
