Dog seems happier, doesn't mind the taste of crumbled vitamin on his food.
I grind these up to a powder and sprinkle on my dog's food for his morning meal. He hasn't turned his nose up to the taste, but I also add a bit of powdered probiotics to his kibble, and I know he likes that. He is 11 years old and his energy seems to have increased a bit but I can't be sure its the Vitamin K or the probiotics. Will continue to use this.

Saved my Dog's Life!
I bought these Vitamin K supplements because our dogs were accidentally poisoned when the vacant house next door was being rehabbed. They had a mice/rat and other vermin problems. My dogs picked up a dead animal in our fenced yard that was probably brought in by a cat or racoon. Both of my dogs became very ill. My Frenchy recovered within a week or so, but my Maltese was just too sick. I took him to the vet, who gave him an antibiotic, but little Basil lost all of his hair, 1/2 of his body weight, and all of his vigor. His skin was bright red and the black spots on his skin (typical of Maltese), disappeared. We thought we were going to lose both dogs and prepared ourselves for the loss. Fortunately, Basil was a fighter and he held on for another two weeks, but with little improvement. Since the vet concurred that he had probably been poisoned, I took matters into my own hands. I bought these Vitamin K tablets and started Basil on a double dose. Within just a couple of days his skin started to lighten up. He started eating again too. He has been on these supplements for about 14 days. His black spots have returned and his skin is a mostly light pink and still fading. He has gained back about 2/3 of the weight he lost, and his hair has just started growing back. I think he is out of the woods thanks to these vitamin K tablets!

Can't see it working
Maybe because my dog is too old?? I started giving her this when she was 14. She's now 16. I was giving her this in conjunction with a few other things but I always questioned if it was doing anything for her. I stopped it for a few months after I started changing up her supplements and once I started giving her these new flower essences, then I noticed a change, so, i really don't think this vitamin K was doing anything positive for her. Plus, she wouldn't just take and eat them. I needed to crush the tablets up and put in beef or chicken broth to disguise the flavor for her. Plus, it's very expensive. I can't recommend it.

Needs taste improvement
Saved my dogs life. We have to coat the pills with bacon grease to get her to eat them which is a pain.

My senior Labrador gives it all his paws up
I’ve noticed a major difference in my 8yr old Labrador’s joint health. He used to limp after a swim day at the beach, but adding these into his daily regime has stopped the limp! They’re expensive, but one bottle should last two months for bigger sized dogs. I pour salmon oil over these and mix with his dinner so he gobbles them with ease. My dog has been on them for three months now and I don’t foresee stopping them anytime soon.

My dog is a puppy again
I am so thankful for this K2 supplement. My older (13yo) female dog started to deteriorate rapidly in her back legs and piddling a lot. She couldn't easily move and was in pain, even to go out. We also had to get diapers for a period because of the accidents in the house while we tried various things. Some to support her hormonally, some to help with joint pain, some for urinary support. I was running the gambit to find the issue. I knew that k2 moves calcium into the bones in humans, so I decided to try this. Within a week she stopped whimpering. Within two weeks, she started jumping up to see us again. No more accidents, no more diapers. No more pain. Hello happy healthy, active elder dog. 🙂

Threw up
My dog has taken this twice now and throw up each time. I did give her a break after the first dose to see if that's why she threw up and she was fine until I gave her another dose.
L**!
My dog is a HEMOPHILIA, and I swear these are keeping him alive!
Hemophilia in dogs is inherited and anything that has it can bleed to death internally or externally for no reason. We are trying to prove them wrong since he already had massive bleeding and since giving these he stopped and he’s survived and doing well. I pray 🙏 this is the remedy and can save lives. We have several things we give but this is a big one! I hope it can save other lives, we love our zeus. Will test blood again
