It was worth it
We can see how a bag of shredded mozzarella would give anyone (including dogs) stomach trouble, but we bet this dog would do it again if he was given the chance. Dairy products aren’t healthy for us humans when consumed in large quantities, and some of us are more sensitive than others, so it makes sense it doesn’t agree with our furry friends either.
Yet, sometimes we eat or do things that aren’t good for us, even though we know we’re going to regret it later, just because it feels right at the moment. In a similar way, this dog probably didn’t think it through before he ate this bag of mozzarella.
