A bit naughty to ask here, but I can find no information elsewhere, and these communities are such a fantastic reservoir of wisdom I thought maybe someone has some ideas.
Usually dogs only become deficient in B12 if vegetarian fed, if the have exocrine pancreatic insufficiency, or chronic diarrhoea leading to malabsorption. None of this is the case for Seamus my nine year old lurcher. But he is going deaf, and developing cataracts so I am very concerned about him. I noticed too that he has started to scrape one foot on the ground every so often and insisted that he be tested for B12, which came back well below the reference range.
The vet has started him on the B12 protocol and I am confident that he won't be left under treated. However I would really like to know where this has come from in case there other things we need to do to keep him well. He has a history of hypothyroidism sine he was 4, and thyroid cancer 2 years ago. Should I be giving him other supplements - I doubt that folate forms a natural part of a dog's diet, but he is in any case fed a raw food which includes a small proportion of green veg.
We are off to the Royal Veterinary School on Wednesday to discuss his cataracts and whether they are operable, and I will ask for their opinion, but would testing for PA make any practical difference, even if possible?
