Try something else. Flavor seems too bad even for dogs that will eat anything.
Buyer beware, seller probably won't honor their promise of "refund if not satisfied". My dog who would eat nearly anything refused to take these supplements after tasting for the first time. In fact this and the B vitamins turned him off his food and medications all of a sudden creating an aversion to anything in a capsule or tablet form. I had him on the Blood Support supplements before these with no problems. I contacted Nutrition Strength based on their statement of "refund if you're not satisfied" in the item description and they ignored my messages. I'm out nearly $100 between this and the B vitamins. I wouldn't have risked spending that kind of money if I had known they wouldn't back up their satisfaction guarantee.

Had to stop giving them
My baby, Piper started vomiting the 4th day after starting them, she ate them fine so it must have tasted pk.. She started vomiting about 45 min after taking her last one and then she was sick off and on all night long, She suffered and it cost me a trip to the vet. My Vet recommended stopping them and recommended that I just buy a highly rated geriatric multi vitamin . It was a Waste of money.

SEVERE DIARRHEA SIDE EFFECT - NO CUSTOMER SUPPORT
This product caused such severe diarrhea to our 11 year old labrador (including blood due to inflammation) we had to stop giving it. She's still having these issues 4 days after last dose. I tried emailing their customer support numerous times with ZERO response. How can you offer a satisfaction guarantee when you won't respond to inquires, concerns, etc?

Does not work.
This supplement doesn’t work and personally i think it’s a huge scam. I took my dog to the vet last year and after a blood test they told me she was slightly anemic. I ordered these pills and gave them to my dog for a year. When I brought her back to the vet this year, her blood test results were almost identical to last years. They had no effect, I wish I could get all my money back because they were expensive and didn’t have any clear, conclusive result in blood tests. Don’t buy these, go to the vet and get a prescribed iron supplement from them instead.

Didn’t work
I gave this to my 11 yr old pit Bull with severe anemia (levels lower than 9) for three months everyday, and saw no improvement in her levels in her blood work (checked by vet every month) I sadly had to switch to another brand and once I did I saw huge improvements (went from a 9 while on Iron Complex to a 14 to an 18 with new brand within a month). I wish this Iron Complex would have worked.

This made my dog sick on the first time using. I do not recommend. I was supposed to receive a refund from amazon but that never happened.
