Gabapentin is preferred over pregabalin due to its proven tolerability in PD and potentially positive influence on motor symptoms [163, 238]
B-vitamins act as coenzymes in numerous metabolic pathways, including carbohydrate and fat metabolism, neurotransmitter production, and DNA synthesis
GPs can prescribe B12 injections following appropriate investigation, which should include: Full blood count to identify macrocytic anaemia Serum B12 and folate levels to confirm deficiency (using laboratory-specific reference ranges) Methylmalonic acid and/or homocysteine when B12 results are borderline Intrinsic factor antibodies if pernicious anaemia is suspected Additional tests depending on clinical presentation (e.g., thyroid function, coeliac serology) When both B12 and folate deficiency are present, B12 should be replaced before folate to avoid precipitating subacute combined degeneration of the spinal cord

Applications in the Exploration of Obesity Intervention Strategies and Drug Development Based on its unique mechanism of action and favorable physiological regulatory effects, NNMTi has become an important candidate molecule for the exploration of obesity intervention strategies and the development of antiobesity drugs
Consider discussing B12 testing with your vet if your dog has: Had chronic or intermittent diarrhoea for more than a few weeks without a clear resolved cause Lost weight progressively despite adequate food intake Been diagnosed with a chronic gut condition, such as inflammatory bowel disease or exocrine pancreatic insufficiency A history of poor early nutrition, such as a recently rescued stray or previously malnourished dog Been through multiple courses of treatment for digestive symptoms without sustained improvement A young dog or puppy that is not developing or gaining weight as expected Causes of Vitamin B12 Deficiency in Dogs Vitamin B12 deficiency in dogs is almost always caused by a problem with absorption rather than a lack of B12 in the diet
