Signs of Vitamin B9 Deficiency

Loss of appetite

One of the signs that your dog may be deficient in vitamin B9 is a loss of appetite. Dogs who lack this essential vitamin may not feel hungry or show interest in their regular meals. If you notice that your dog is not eating as much as usual or is consistently refusing their food, it could be a sign of vitamin B9 deficiency.
