Oh I see. Do you feed him other beef products? Yes beef products can all be at risk for this if the manufactuerer is using poor quality cuts of meat that contain the thyroid gland. But you won’t know until there is a recall.
As far as the anxiety/panting goes, yes dogs can certainly have anxiety, but many dogs are anxious because they are not being properly fullfilled in their life. Corgis are a herding breed and have strong drive and desire to work. Is he allowed to do any herding or does he do any sports were his mind is being challenged? Even something in your backyard like having him hunt for things or many Corgi owners commonly use whats called a “Jolly Ball” to teach their Corgis how to herd. You can buy these at most pet stores. If he’s given a job and a purpose you may find that he is more well adjusted. You could even walk him and allow him to wear a backpack to carry items of yours (not too heavy, but approrpiate for his size). If I do not exercise my dogs, especially my 4 year old, I notice they are a lot worse behaved and destructive. The same can be true for anxious dogs.
