Look at the ingredients, may have milk and meat.
it seems for you as a human food..? its a dog food (for does who have dogs, or just to save on S&S!)
I'm no posek, but there is a concept of something being assur b'hanah
right & important to be aware about, thanks! but as per what i checked i didn't found anything dairy in this specific 1 'Sausage Links' only beef, (the other 1's prob. contain like the Beef & Cheese www.amazon.com/dp/B00IEXR00I?tag=admarketus-20&ref=pd_sl_aE8182378361B0BBAF28836E7C&th=1)
Even the Sausage links contains meat and milk. 2nd ingredient is beef, 9th is dried cheese. Not all meat/milk mixtures are assur b'hanaa (e.g., if they aren't cooked together), but hard to tell from just the ingredient list. Best to stay away from beef and milk mixtures in pet foods. But I am no posek, so ask your LOR if you care.
to be fair, it is food for your dog, you wouldn't eat it yourself.
