What fish oil and fish protein is in this diet?
Answer by ChewyNov 03, 2020
Forza10 Active exclusively uses small fish (anchovies or herrings), captured in the open sea and processed whole, and particularly rich in precious poly-unsaturated fatty acids. These fishes not only feature exceptional digestibility and protein values, but also offer the natural characteristic of transforming fat into muscle, helping to develop a lean and muscular body.

Highly recommended!

My Aussie has a pretty sensitive gut and has eaten various types of food through the years. Last year I tried one of the other Forza 10 kibbles and she did really well with it but I got tired of the fishy smell and switched to a different brand. After struggling with a recent bout of very bad diarrhea I decided to put her back on this brand and got a bag of the colon diet. After 2 days she is markedly improved. I wouldn’t say it’s her favorite food but she’ll eat it and her gut is very happy. It’s worth the fishy smell. Storing it in an airtight container helps. Interestingly, her poop isn’t all that smelly - it’s just the kibble itself that has the strong smell. Also I’ve noticed that her poop is very dry although she’s been drinking normally and seems well hydrated. And this food seems to make her poop more throughout the day, as others have noted in their reviews. All in all I’m very impressed and optimistic! Thanks, Chewy, for carrying this brand.

Working so far!

Our 1.5 year old cattle dog mix has had soft stool ever since we adopted him a few months ago, but last month he he started having diarrhea, lethargy, and rapid weight loss, even though he was eating plenty of food. Even after multiple vet visits and exhaustive testing including various blood tests, fecal exams, urinalysis, and an ultrasound, our vet left us without answers and suggested we try an elimination diet using prescription vegeterian hydrolyzed kibble to see if that helped. After a month on the prescription diet and nothing else, our dog was still losing weight, having regular episodes of diarrhea, and his eyes, coat, and expression were dull and unhealthy looking. With our vet at a loss for what to do, we desparately searched the internet over and over again for possible solutions, and discovered Forza10. We were impressed by the outstanding reviews and testimonials from pet parents like us who couldn't find solutions through their vet, and stumbled upon Forza10 the same way we had. We took a chance and ordered an 8 lb bag of the Colon Diet Phase 1 dry food, transitioned him to it in 1 day, and literally saw a huge difference by the following day. Our dog gobbled the food up, his poops were high quality and the right color, and he started looking a bit brighter-eyed. After a week on Forza10 Colon Diet he is visibly starting to gain some weight back, and even just a little weight on is a big win for us. We are giving him a plain scrambled egg a couple days a week to give him some additional protein/fat, and he hasn't had diarrhea since day two on this food, and his coat, eyes, and general comfort are improving every day! Few things to note: - This food is stinky (like a mix of fish and stinky cheese)! Our dog loves it, but I recommend keeping the food in an airtight container and feeding your dog outside if you are sensitive to smells (or have guests arriving soon!). - This makes our dog's poop solid and high quality, but at first it was a little on the dry side. I recommend letting the food soak in a little lukewarm water for a few minutes before feeding to help make poops the best consistency. - This makes our dog poop much more frequently than he used to, and it's not uncommon for him to have small, great looking poops 5 or 6 times a day. With the good poop size/quality and other improvements, we aren't too concerned by the increased frequency, but will keep our eye on it. He just poops like clockwork now before breakfast around 30-40 mins after each meal (we feed him 3 times per day) during his evening walk, and sometimes before bed. HIGHLY RECOMMEND. Don't be scared to try this food just because it's not on your vet's radar. Be your pet's advocate and trust your instincts - the proof is in the poops!

The best food so far

We had trouble with our Pomsky puppy from day 1 with soft or loose stools, always trying to figure out what was causing it. After he was diagnosed with colitis, he was put on Hills Biome. It kinda worked, but we still had so much inconsistency. A few months ago we decided to give this a try after I stumbled upon it while seeing what others have given their dog for colitis. HUGE DIFFERENCE. We have barely seen a loose stool since we started him on this. Since our dog will eat practically anything, I can't say that he likes this any less or more than all the other foods he will happily chow down, but it did solve our big problem. Highly recommended!

Stopped my dogs spastic colon in a day or two!

My dog was having a spastic colon for several days. Knew she didn't eat anything she shouldn't have, tried many different things to help calm her gut down, but nothing really solved the problem. Went out on a whim after seeing the reviews for this food and SO GLAD I did! My dog stopped having frequent very loose stool within a day or two!

Saved our yard and my sanity

We tried multiple different types of food for our 1.5 year old Great Dane's sensitive stomach and he continued to have loose stools on ALL of them. This food was a last ditch effort before trying an expensive prescription diet, and I am SO glad we tried it. We began this food with no transition period per the bag's instructions and our dog's stools were instantly solid. I was amazed. Since this isn't large breed specialized, we have to supplement with vitamins and supplements to ensure he receives all the vitamins and nutrients he needs, but we don't even mind since this food helps him so much!

Worth Every Penny

Our 12.5 year old shepherd mix has had gut issues off and on for years. Saw some improvement when he started a salmon/sweet potato diet, but over time and with age the problem persisted. He was going through one of his bouts of liquid stool; had him on the bland rice/pumpkin/probiotic diet and our vet added Flagyl. No big improvement until I read the reviews for Forza10 Colon and decided to pay the price and see how Webster responded. No transition phase to the food was needed; he ate it all up first bowl offered. Formed stool within 2 days! YEAH! This stuff is worth every penny and minute saved cleaning floors and carpets.

Best Solution So Far

We adopted a rescue Pom 1 year ago. Food was immediately an issue. She had intermittent diarrhea for 10 months. She would be ok sometimes for as much as 4 weeks but it always came back. Nothing worked—we tried everything—except antibiotics and we were getting to the point where we considering lifelong use of metronidazole. She’s been on this food for almost 3 months and, although she still has occasional diarrhea, it is much less frequent and of much shorter duration—a couple of days v weeks. Definitely grateful to have found this food.

Dog is not a fan

My dog typically isn't picky eater. This food may do what it states, but my dog will not eat it unless I cover it in kefir.
