Yorkie/Chi mix has had bloody diarrhea/mucus/nausea for the past year. Identified poultry may be an issue, so removed poultry from diet. After months of digestive issues and many tests, blood test indicated low B12/folic acid - so started injections. Was great for about 8 months on fish-based food. Company changed formula, issues started again. Now she is on lamb/sweet potato and seems to be tolerated - but - the day of the B12 shot she sleeps most of the afternoon and doesn't eat until later and the next day she doesn't eat most of the day and often experiences distress/bloody mucus diarrhea after which she starts to eat. Happens almost every week after the B12 shot. I see no indication of side effects from B12 injections.

My dog got a vitamin shot today, I'm guessing it's the vitamin b12 and right after he got that we got home and he threw up everything he had ate this morning .. he looks very weak and sad. I gave him suero since he wasn't drinking any water . Is this a side effect on the vitamin shot? And should i not worry or should i take him to a vet if it doesn't stop?

Have you ever heard a connection between shakey puppy syndrome and low B12? Could this condition be treated with B12 supplements? My 6 mo old dachshund mix still has head-shakes and very weak, underdeveloped hind quarters. It doesn’t slow him down but he walks/runs like a drunken sailor and is constantly falling. Our vet (and the internet) says to wait it out but I was just curious. Thanks

She has had gassy stomach upset her whole life. Has been eating high grade dog food whole life; recently (abt 1 year) switched to no grain & appeared to be better for a while then back to more frequent & extreme symptoms. Had 2 B-12 shots in less than a week yet blood tests showed low B-12.. lost almost 1 lbs in abt 1 month, appetite is good; has been on Hills prescription d/d Salmon diet (hard & wet food) for last month in a half (thought she was allergic to chicken)has been actively treated for first gassy stomach then colitis, then iBS then colitis again. Blood tests are all normal except extreme low B-12. Dr wants to do biopsy& suggest weekly B-12 shots but i’m Reluctant for invasive biopsy.Has been seen by 2 vets. What could it be? Is biopsy my only choice?

After having diarrhoea on and off for a few months, despite trying the usual bland diet etc. our dog Bailey started getting constant diarrhoea with more frequent poops a day than usual. Our vet did a poo test and found initially that she had a worm, she didn’t say which one, so was given the injection for this as she was due one anyway. She was also given antibiotics. Unfortunately the diarrhoea continued and we took her back. She had some blood tests done and found she had a B12 deficiency. More antibiotics. By this time she had lost quite a bit of weight and her spine and ribs were starting to show. She was given a B12 injection which we were told she would have once a week for four weeks. But, we were also told that if she hadn’t improved by the time the second one was due she would need a scan. We took her back for her second one and she had lost another 1/2 kilo in a week. We were told that there was no point in giving her the injection and a scan has been booked to check for something more serious 😔 Why would she not have the injection and what else could this be? She is fine in herself apart from being hungry all the time to the point of eating her own poo! Could it be a thyroid problem? Not sure if this has been tested.

Our 4 year old female Great Dane has had diarrhea on and off for months, (she has never been quite normal since we got her at 10 weeks and the vet has never said anything at any of her annual check ups). Back in December our family mentioned she had become very skinny (not something you notice really when you see her every day). Her appetite and water intake has not changed. Her eyes were icky and she was constantly scratching, so the vet put her on allergy meds, antibiotics, and eye drops. Nothing really changed so we took her back to the vet, they did blood work and it came back with very low B12 levels. She is now eating a hydrolyzed protein, vegetarian food and is taking a B12 supplement. She has been on this routine for about a month. She has not gained any weight and still very lethargic at times. Last night I noticed that she shivers when we inhales, also that the edges of her ears have become dry. This morning she had no motivation to go outside and potty or even get out of bed..Could this be something more than a deficiency?
