Helps our pup!!
Our Shepherd has EPI and this has really helped him. In addition to monthly B12 injections, we give him these B12 capsules to help him daily. They are easy to use, have no smell and they really help our pup stay healthy!

Great value for your pets
Had my dog on these for years due to a low B vitamin issue. The value and quality of this B12 pill is great. No issues getting the dog to take them and helped correct the B vitamin issue.

It’s helped my dog and no gi issues what so ever !
Update: 12/20/24 When my dog got real sick with vestibular syndrome and renal disease in the late stages, this didn’t work….not even B12 solution injection was the answer. It is a better and healthier option compared to drugs, I’d still say give this a try first before drugs that can potentially cause more renal problems. I bought this supplement because my 15 yr old (8 lbs) German spitz wasn’t eating his food that even included his favorite “boiled chicken”. I bought this in hopes of getting him to eat on his own to make life easier for me and of course more enjoyable life for him, also to help him with his energy. I started supplementing very little because I saw the negative reviews from people saying their dog got very sick. Each capsule can be given to a dog from 1-50 lbs and that to me sounds like a high dose for an 8 lbs dog so what I do is pour the capsule contents on a plate and divide it to 6 parts. The first couple of days I was just giving him 1/6 of capsule with his food, but once I saw he was doing well with it, I started giving him 2/6 of capsule daily. 1/6 with breakfast, 1/6 with dinner. I’m giving all the details and the exact measurements in hopes that someone with a small dog like mine can use this as a guideline to introduce this to their dog without causing gi issues. I’m very happy to report my dog has a much better appetite, he eats his home cooked meals now that isn’t just boiled chicken , it’s chicken and a whole bunch of vegetables and some fruit, although he still doesn’t want to eat his commercial made dog food ( honest kitchen limited ingredients turkey powder). His energy level is so much better. Cognitive wise, well he is 15 yrs old and as long as he doesn’t get worse and forgets to follow me around the house then I’d say this supplement is doing something. I must mention, I only add this supplement to his food that he doesn’t like to eat along with the rest of his supplements that I syringe feed him. I think supplements and meds for the most part always should be given with food unless it specifically states otherwise but some of these supplements can alter the taste of the food so if you guys have a picky eater like mine, don’t add supplements to the food they actually like. Find a different way to supplement them, syringe feed or mix it with small amount of salt/oil/sugar free peanut butter.

Young dog with EPI issues
I love that this product works. My dog has only had one bad day since I have been adding to his meals. He now eats every morning and his “deposits” in the backyard are normal and regular. Since using this product over a period of 2months he has gained back the weight he lost and seems like a different dog.

Superior Product over others that claim the same!
This beautiful chocolate lab was born with a lot of health issues. Anal glands in overdrive. Unstable digestive issues that were ongoing and causing soft stool to full on diarrhea. Hundreds of dollars spent at multiple visits to our vet, them doing the same protocol again and again never digging further into what is causing her problems. You know how it goes…just throw a bandaid on it, just write an expensive prescription for it that comes with a ton of side effects. Not to mention her spaying was botched, 6 months of internal infections, which lead to low grade urinary incontinence with a risk of UTIs. 11 puppies in her litter, and we get the one who has health problems. Not to worry, I’m a dog mom who doesn’t give up. I do the research, I figure out the causes. Her body doesn’t absorb regular vitamin B12. Thank goodness for WonderLabs Pet Factor B-12! Her health is improving! Her stool is healthier! She just on one a day right now and her improvement in a week is significant! The vitamin B 12 injections at the vet are very expensive. This is a much more affordable way to help a dog’s body absorb Vitamin B12! The quality of this product is far superior to others that claim the same benefits. Our dog has always had high energy levels, so this hasn’t changed anything. The size of the pill is small enough to hide in a spoonful of canned food. My dog doesn’t notice it, so I guess the taste is minimal. I fully recommend this product for any dogs with ongoing soft stool issues. It’s worth a try. 180 pills! That’s a 6 month supply at 1 a day or 3 months supply at 2 a day. Far more affordable then B12 injections at the vet, and less stress on the dogs.
