Salmon & Oatmeal Skin & Coat Health Kibble Dog Food

⚪ Transparency signal: 'natural flavor' in pet food is most often animal digest — hydrolysed animal tissue sprayed on the outside of the kibble to make it palatable. It is not required to name the species. The concern is not toxicity, it is that a bag can list an unnamed animal product and disclose nothing about what it was.

⚪ Safe synthetic at label levels: pyridoxine HCl is synthetic vitamin B6, and it's the standard, effective form used across pet food. Dogs require B6 for protein metabolism and neurotransmitter production, and deficiency causes anaemia and seizures. The reason for noting it at all is that B6 has an unusually narrow window at the top end for a B vitamin: chronic excess causes peripheral neuropathy — nerve damage in the limbs and loss of coordination. That's a concern for over-supplementation, not for its presence in a balanced food.
